downloading parts of a html page on an event - html

I am developing an universal windows app. I need to download a webpage and extract images from it.
I got the html code and extracted the links to images and downloaded them. The thing is, the site has infinite scrolling (like facebook). When I scroll down to the bottom it loads more images. I am not able to incorporate this into my app. I am a beginner and have very little knowledge of web development or windows app development. This is my first app. I am stuck and have no idea how to proceed. I don't want to use webview as it displays ads from the site and other unnecessary contents. I only want the links to those images. Please help me go past this situation. I need a way to download the new html content that the site loads when user gets to the bottom or some other way to get the image links.
Thanks in advance.

You may or may not be a me to implement this specifically because of the reason you stated. You need to determine how the site loads this information. First I would download Fiddler and in turn enable https connect logging so you can see your encrypted traffic going through Fiddler. Btw the Web View has events you can hook to see loading URLs, etc and it can also be hidden.
So again you need to first understand how the site you want to do this on works and emulate that, assuming they don't have an api already to give you this information as mentioned I'm the comments.
When you do that, come back with code examples and you'll get better help.

Web browser plugin for bulk domain

I managed school websites which around 100 domains.
My boss asking me what is an easy way for him to get and see front page for all the website on the different domain.
Is there any web browser plugin can solve this?
This will be easy if I can give him domain.txt and plugin will do the rest.
Thanks in advance.
You should solve this server-sided:
Create a scripted page, that uses iframes to show a tiled view of the target pages
Make this script configurable via a domains.txt, a database or whatever works best for you
Point your boss to tis page

Pictures sometime don't load on my website

I've made a website which displays images hosted on other sites using the html src="http://......" tag, however sometimes some of the images won't load. This appears somewhat random, and I don't think it is a problem with the links themselves.
I display a lot of images, so I am wondering if this is a common problem when trying to load many thumbnails from another site. Is the best solution to host all the thumbnails on my own server, and if so, is there an efficient way to do this (so I don't have to manually download and link to every image)?
Thanks
Is way better to host it on your own server.
Because if are all from other servers, you must connect to all servers and download it.
It causes worse response and increase the time required to load the page.
To the image and links downloading - I think it is possible, just go on google and try to find some advanced html page downloader. I had one and it worked directly the way you want. - can't remember the name..
(also sorry for my bad English)

Is there any way to permanently alter how a webpage displays on the client-side (without server access)?

Firebug lets you edit individual web pages locally, with live updating so you can see the effects of your changes right away. Unfortunately, these changes are lost after the page is refreshed.
Is there any way to make these changes "sticky" in some way, such that repeated visits to the site would reload your own customized html/css that you edited? I'm thinking perhaps some sort of Firebug feature that I'm missing, or another plugin of some sort...
Just to be clear, I'm not talking about websites I have server side access to. I would simply like to be able to reposition the content of some pages I visit frequently so it fits better on my monitor setup, which I can do in Firebug but I have to do it every time the page loads (I would like to be able to avoid having to do that).
You should make use of the Greasemonkey and / or Stylish addons for Firefox.
These where originally developed to do exactly what you intend to achieve.

Faking website integration

I am working on a prototype for a project that is somewhat similar to the facebook's "like" button. Basically it's an embeddable piece of code that can integrated with any website.
I am looking for a way to fake this integration for a demo. Basically I want to show a familiar web page (like http://www.cnn.com) with my code already embedded. Since I obviously can't do the actual integration right now, I need some way of faking it.
The only thing I can think about is to use http://www.httrack.com/ to download the page I want, and then change it locally. The problem with this is that it is clear that the page is hosted locally and not on www.cnn.com.
Is there a better technique for doing this?
If you use Firefox browser, you can use Greasemoneky and with JavaScripts, embedd your content inside that page. You can eaven add events, that will open some popup windows, etc. to show action of such a script.
That is easy approach, there are ton's of examples in their forum, and good documentation, how to use it.
You can write your own userscript (i.e. greasemonkey) to modify the page on the fly.
Even though I think it's a bad idea to do this (not sure if stackoverflow allows to ask such questions), but what you can do is edit the hosts file (if you're on windows) and add a line
127.0.0.1 www.cnn.com
it means that when you visit the website cnn it will display the domain name in the browser but it will use your localhost server to display the content.

fetch html code, edit it and load it with web view

am new to the iphone development and I have a problem to display a certain site that is essential for my app.
What I want to do is to display this site with no horizontal scrolling and with a text size that can be read without zooming in or out.
As far as I understand this is impossible without mess with the html source code.
But I have no idea how to fetch it, and most importantly how to modify it and with which tools I can do that.
And then how I can load that code in my web view.
I know that I ask to much but I want to learn how to do this stuff and I don't search for someone to give me a ready solution but to point me in the right direction.
If I understand your question correctly, you want to render a site which is not under your control and add certain style changes (font size, no-scroll, etc) to it.
If what you need from the page doesn't change (i.e. it's a static page), then this should be fairly easy. You simply copy the code from the source by saving the page as an HTML file from your web browser. From there, you can use your favorite HTML/CSS editor to make the changes that you need and then host it yourself.
If you don't want to host the code yourself and/or the page is dynamic then you're going to need to give us more information to adequately answer this question.
