It looks like you're copying the raw HTML from this file:

"C:\Users\alex.GFH\Desktop\Email\beefree-s09uuvnlono.HTML"

As the message body of your email.

My psychic powers tell me that you've got tags inside your HTML that are pointing to relative locations. e.g. . As such when the HTML email is opened in someone else's browser or mail app, the renderer has no idea where to fetch "picture.jpg" from.

And even if it did have the full URL, most mail apps won't fetch URL images by default until the user acknowledges the privacy risk.

I think if you want your images to just show up when the mail is opened, inline the image bytes directly into the tag. You base 64-encode the image and stick on a header (e.g. data:image/png;base64, or data:image/jpeg;base64,. That becomes the src attribute.
