package image works in style but not in img - html

I am using ng-cordova, I have stored an image in a subdirectory of cordova.file.dataDirectory, and am unable to load it via img[src] but I can load it via [style], do I have to do anything special to make it work in the img[src]?
$scope
{
"Image":"file:///data/data/{package}/files/{subdir}/{imagename}.png"
}
Works
<div style="background-image:url({{Image}})"></div>
Doesn't work
<img src="{{Image}}" />

This was a silly error, I forgot to check my $compileProvider service. I had it working for filesystem but not file.
$compileProvider.imgSrcSanitizationWhitelist(/^\s*(https?|local|data|filesystem|file):/);

How to load image (and other assets) in Angular an project?

I'm pretty new to Angular so I'm not sure the best practice to do this.
I used angular-cli and ng new some-project to generate a new app.
In it created an "images" folder in the "assets" folder, so now my images folder is src/assets/images
In app.component.html (which is the root of my application), I put
<img class="img-responsive" src="assets/images/myimage.png">
When I do ng serve to view my web application, the image does not display.
What is the best practice to load up images in an Angular application?
EDIT: See answer below. My actual image name was using spaces, which Angular did not like. When I removed the spaces in the file name, the image displayed correctly.
In my project I am using the following syntax in my app.component.html:
<img src="/assets/img/1.jpg" alt="image">
or
<img src='http://mruanova.com/img/1.jpg' alt='image'>
use [src] as a template expression when you are binding a property using interpolation:
<img [src]="imagePath" />
is the same as:
<img src={{imagePath}} />
Source: how to bind img src in angular 2 in ngFor?
I fixed it. My actual image file name had spaces in it, and for whatever reason Angular did not like that. When I removed the spaces from my file name, assets/images/myimage.png worked.
Angular-cli includes the assets folder in the build options by default. I got this issue when the name of my images had spaces or dashes.
For example :
'my-image-name.png' should be 'myImageName.png'
'my image name.png' should be 'myImageName.png'
If you put the image in the assets/img folder, then this line of code should work in your templates :
<img alt="My image name" src="./assets/img/myImageName.png">
If the issue persist just check if your Angular-cli config file and be sure that your assets folder is added in the build options.
Being specific to Angular2 to 5, we can bind image path using property binding as below. Image path is enclosed by the single quotation marks.
Sample example
<img [src]="'assets/img/klogo.png'" alt="image">
Normally "app" is the root of your application -- have you tried app/path/to/assets/img.png?
1 . Add this line on top in component.
declare var require: any
2 . add this line in your component class.
imgname= require("../images/imgname.png");
add this 'imgname' in img src tag on html page.
<img src={{imgname}} alt="">
You can follow the below steps in Angular 8+
Step 1: load the image as below in component
const logo = require('../assets/logo.svg').default as string;
#Component({
selector: 'app-show-image',
templateUrl: './app.component.html',
styleUrls: ['./app.component.scss']
})
export class ShowImageComponent implements OnInit {
logo = logo;
constructor() { }
ngOnInit() { }
}
step 2: Add the logic in html file
<img [src]="logo" [alt]="'logo'">
If launched without further configuration, you will see a strange error:
ERROR in src/app/app.component.ts(4,14): error TS2580: Cannot find name 'require'. Do you need to install type definitions for node? Try `npm i #types/node` and then add `node` to the types field in your tsconfig.
Do as suggested – add the #types/node typings to your project by running npm install #types/node and edit tsconfig.app.json to set:
"compilerOptions": {
"types": ["node"],
...
}

resource
It is always dependent on where is your html file that refers to the path of the static resource (in this case the image).
Example A:
src
|__assests
|__images
|__myimage.png
|__yourmodule
|__yourpage.html
As you can see, yourpage.html is one folder away from the root (src folder), for this reason it needs one amount of ../ to go back to the root then you can walk to the image from root:
<img class="img-responsive" src="../assests/images/myimage.png">
Example B:
src
|__assests
|__images
|__myimage.png
|__yourmodule
|__yoursubmodule
|__yourpage.html
Here you have to go u in the tree by 2 folders:
<img class="img-responsive" src="../../assests/images/myimage.png">
for me "I" was capital in "Images". which also angular-cli didn't like. so it is also case sensitive.
Some web servers like IIS don't have problem with that, if angular application is hosted in IIS, case sensitive is not a problem.
Try not give space while loading the images.
Instead of
<img src='assets/img/myimage.png' alt="">
try with string interpolation or Property Binding to load the source image as best practice.

ASP.NET MVC Img tag not loading image when loading path from database

I am attempting to make a photo gallery asp.net MVC website, and part of that involves the setting of the src to a local folder that contains images.
#model MyProj.Models.PhotoIndexViewModel
<div class="row" id="tableSearch">
#foreach (MyProj.Models.VideoModel photo in Model.PImgList)
{
<div class="col-sm-3 thumbnail">
#Html.DisplayFor(model => photo.Title)
<a href=#Url.Action("View", new { id = photo.Id })>
<img class="img-responsive"src="#Url.Content(photo.ThumbNailPrev)" alt=#photo.Id /></a>
#Html.HiddenFor(m => m.searchTerm)
#Html.Partial("_Tags", photo)
</div>
}
</div>
The ThumbNailPrev is "~/Pics/.jpg", which relates to a folder in the main part of the project. The issue is that the image does not appear. When I check the image using inspector is says it isn't found at /Pics/(photoid)/jpg. I don't understand why it is doing this, as my pics and the image itself are present at that location. I have also made sure to include the folder in my project, but it still doesn't seem to find the image.
UPDATE:
I just tried something and confirmed it is something to do with the way I'm calling the path from the database. As if I hard code the EXACT same string as the one in the database it works. The question now is why does that work?
For want of a letter..
I finally determined the problem, and it was a pretty dumb one. In code I am saving a jpEg image, but calling it via jpg. After changing the .jpg to .jpeg in the view everything works... If you are having a similar problem, check and make certain the file extension is correct.

ng-src not showing up for my img array

I have a simple image viewer webpage on gitpages but before I push the next group of images I want to condense all of my images into an array using angular.
The test I have made here uses only 4 photos that are in the same folder as every other file.(they are jpegs)
my js file is set up like this with a factory for the array and a controller.
angular.module('beamModule',[])
.factory('imageFactory', function(){
return {
getImages: function(){
return ['beam1.jpg','beam2.jpg','beam3.jpg','beam4.jpg'];
}
}
})
.controller('Photos', function(imageFactory){
this.images = imageFactory.getImages();
});
I don't think anything is wrong with this array but maybe I am overlooking something?
The HTML that I am using and the section that is giving me trouble when I check the developer tools is below.
<div class="imgcontainer" ng-controller="Photos as photosController">
<img ng-repeat="src in photosController.images"
ng-src="beamModule.js/{{images}}">
</div>
I am not sure if I am supposed to be using an ng-class attribute in the css or if there is something else that needs removed?
The developer tools are returning this value for each of the images (they are repeating just not showing)
<img ng-repeat="src in photosController.images" class="ng-scope">
Why is the ng-scope class being put in here and the ng-src is being removed?
EDIT FIXED
Ok to the person who answered so quickly and simply you are the real mvp here.
You said to change the ng-src="beamModule.js/{{images}}" to read {{src}} instead.
Once I tried this it still didnt work but then I checked the dev tools and noticed it was attempting to pull the files from the js file and not the actual file so I just changed it to this and now it works great! Thank you.
ng-src="{{src}}"
The ng-src attribute needed to point to the repeat instead of the js file.
ng-src="{{src}}"

Path for resources html difference between "images" and "../images"

I have a html located at www.domain/folderOne. My images path's at www.domain/images.
I found out that the file mywebpage.html located at www.domain/folderOne can get the images displayed with either
<img src="../images/7.jpg" alt="Text" style="width: 800px; height:400px; " id="text">
and
<img src="images/texts/6/7.jpg" alt="Text" style="width: 800px; height:400px; " id="text">
I don't know why both work. Could anyone provide an answer? As an extra information, I am making the html file change the location displayed in address bar after it is loaded with:
<script type="text/javascript">
history.pushState(null, null, '../SuperWeb');
window.addEventListener('popstate', function(event) {
history.pushState(null, null, '../SuperWeb');
});
</script>
You likely either have a symbolic link in the directory tree that stores your web assets on the server, or a web server mapping (e.g., a rewrite rule) that maps calls from one URI to the other. Hard to know without knowing more about your server setup, but it's not an intrinsic feature of HTML. I will point out that it's a good practice to use site-relative links (e.g., /path/img.jpg) rather than document relative (as you specify above), as it makes it hard to migrate content to different directories.

How do you change/locate the default icon of the Authentication Login in DNN?

Here is the code when it's compile, but how would you locate it?
<div class="SteelBlue01_style">
<div class="SteelBlue01_top_bg">
<div id="c_head">
<div class="c_icon SteelBlue01_top_height">
<img id="dnn_ctr_dnnICON_imgIcon" src="/Icons/Sigma/Authentication_32X32_Standard.png" style="border-width:0px;" />
</div>
<div class="c_title SteelBlue01_top_height">
<span id="dnn_ctr_dnnTITLE_titleLabel" class="c_title_black">Account Login</span>
</div>
I don't know if this is configurable from the Admin area of DNN like the site logo. If it's not accessible, here is a way around it...
In the provided sample the default icon is at the path, /Icons/Sigma/Authentication_32X32_Standard.png.
If you want to change it, you could replace that file with another image file that has the same name. That way, when the default location used, it will be retrieving your file.
One warning about using this technique. Since you are replacing files put there during installation (either of DNN itself or of a module), if you update, there is the risk that your file will be overwritten with the one provided by DNN or the module. Be careful during updates. If you start to do replace core components, make sure you keep a list of your customizations so you can check them after updating.
