HTML email template images are not displaying in Outlook and Webmail - html

Thanks Everybody in advance, I have created an email template with banner image and with some widget image.
Actually instead of giving the path of the image which is stored in the server I used a code which is the decode of base64.
I used https://www.base64-image.de/ this online converter will convert the image to base64 decode for my image.
Actually my plan is instead of loading the image from the server I was using the base64 decode image so that it will be displayed in all emails like Outlook and web mail.
By referring the google I got this idea but in outlook and web mail it's not working.
After converting the image using https://www.base64-image.de/ I got the image code like this

The email client is probably blocking this type of image, or in fact any image by default. I imagine they believe that base64 encoded images present too much of risk in terms of malicious attack.
When designing emails you should expect that images will never be seen, so make good use of alt text and never have important information (e.g. text) in images on emails.
A lot of html emails include a "email looks wrong? view online HERE" link to get around this issue.
If you are worried about server costs for image hosting I would suggest using a service that will send and host resources for you e.g Mailchimp and Campaign Monitor.
These are good resources on the subject:

How to fix HTML-Email Images Breaking in different email clients

Hi I'm using power automate to send email with images, But it breaks on google but in outlook it works perfectly fine.
This is the result on Outlook:
This is the result on Gmail:
I've already use Base64 Encoding and I don't know what to do next.
You have given us the answer: you used base64 encoding when there is not good support for that across email providers. See https://www.caniemail.com/features/image-base64/
Upload the images to a website or other public repository (a CDN or storage place publicly accessible), and then use <img src="https://www.place.com/imagehere23423423.jpg" ...>

Is an HTML image in an email rendered before or after the recipient receives it?

I have a task to send an email containing an HTML image to recipients without using the internet (SMTP is okay). I need to do this in informatica BDM using a Java transformation. I have the code working with a hyperlink reference to the image but when I try to locally access the picture via absolute path, the image is not added (seems to be an Informatica issue).
My question is:
if I use the hyperlink to point to the image will my server try to add the picture before sending the email, or will the picture be rendered by the clients machine when they receive the email containing HTML?
Here is what my code looks like
emailDescription = emailDescription + "<center><img \" src=\""+ path + "\" alt=\"Logo\" align=\"middle\" title=\"Logo\"></center><br>";
where path is just a variable containing a link to the image
An image in an email is rendered by the email client, but the image can either be fetched from an URL or embedded in the email. If you don't have a web server to serve the image from an URL, you should look for embedding techniques (which unfortunately I don't know).
A quick search for embedding images showed me that various email client behave differently, mostly to protect receivers from spam and malicious images or links. You may have to test with some clients used by your target audience.

Alternative to base64 Encoded Image sources (E-Mail Signatures)

I am trying to generate email signatures for my entire company so I am using a script to fill in an HTML template with each individual's information and generating an HTML file that I would like to use for the signature. The generation of the HTML works fine and I can load the HTML into chrome and it displays 100% correctly.
I would prefer to not have to host these images somewhere at the moment and would like them to be embedded in the e-mail. We can achieve this by using outlook on each individuals machine to create the signature by hand, but again we want to avoid that. Ideally, we will generate these templates and then automatically put these files on each employee's computer so all we have to do is select the signature from outlook.
The problem we are having is that when we do this, the image does not load. It seems that outlook won't allow base64 encoded images? I've tried to work around this by trying to attach the image to the email and then referencing it, but this doesn't seem to work either. I used this template. I got the boundary from a test email I sent myself, but I don't even know if this is a good way to go about this either.
In short, is there a way to create an .htm file for outlook signatures that includes the image inside the .htm file?
External image file that will be added as an attachment is the only way - Word (which renders HTML messages in Outlook) does not support base64 embedded images.
Try to create a new signature with an image in Outlook and see how they reference the images.

Is it possible to include image in email as attachment using a cid and web server URL?

I am working on an email signature to be sent from Outlook and Outlook web client that will be applied to all individuals in a company using adolsign (a third party tool that generates an email signature based on AD information and an html template).
It needs to contain a logo.
Based on my research, images linked directly from a web server as below cause two problems. 1. They are often blocked by web clients for security reasons and 2. they are unavailable when the user has downloaded an email and opens it offline.
<img src="http://www.myurl.com/myimage" width="142" height="30" >
Embedding the image using SVG or a 64 bit encoded data tag doesn't work in Outlook, so that is not an option.
I believe that using the cid tag to create and reference a hidden attachment is my best option for this particular client, but I'm struggling to get this to work using a url. Using a network file path is not a great option as it won't resolve for users sending emails from the web client. I'd like to use something like this but it doesn't render when I open it in Outlook:
<img src="cid:http://www.myurl.com/myimage" width="142" height="30" >
My hope is to get Outlook to create and reference an attachment in the email that is downloaded from the url when the email is sent.
How do I accomplish this? Is it possible? Please let me know if some of the assumptions I am making are incorrect.

Embedding a static image in html email

I have a requirement where in I have to to send an email to customer, I have an email template coming in from database (blob data). And there is an header image which should be displayed in the email when customer opens the email.
The image will not be available on server
The image will not be available online (i.e in any website online).
This image is a client header. How can I embed the static image without referring to any location or any online website.
Yes this is possible by encoding the image in Base64
For more info see this Displaying images in webpage without src URL
Finally you will end up with something like this in your html message:
<img src="data:image/png;base64,iVBORw0KGgoAA.........very_long_string....." />
The general solution to this problem is multipart MIME. You add the image as a part of the email message and use a cid reference in the <img> tag.
However, you're probably using some library to send this email, in which case it probably has an API for creating multipart MIME messages.
in case you don't want to load images from the server then only embeding of image with base64 can workout.
