Why does Include URL of Images exist?

[gamebeaker]

As I understand it: If a image is .jpg etc. the source URL is included as a comment <!-- https://example.com/img.jpg --> (doesn't matter if Include URL of Images is checked) If "Use <desc>https://example.com/img.jpg</desc> Both are meta data that the user can't see.

If the user can't see it why is that an option?

Todo: If this should be kept in WebToEpub change the comment after the img element to the alt attribute (is the same as <desc> for svg) and only to be included if the option is checked.

edit: I found the commit and it references #22

@gamebeaker WebToEpub records where it gets all the chapters and images from. I think the idea was that some sites provide multiple images. So (at least in theory) those who wanted to could use this to find the alternate resolution images, and replace. That said, the source URLs are now recorded in the content.opf file as <source> elements. So, we can probably remove adding the URLs to the chapters.
