I made this because I needed to include a few small images into emails I'm sending for a separate project. I didn't want to annoy the user with the "allow images from this sender" message, so I needed them to be pure html/css. I couldn't find a tool that would make the conversion with inline css, so I made one myself. It can't handle large images because the css is inline, but that's the trade-off for being able to email them. Can you think of anyone who would pay for this? Is there a feature I could add that would make this worth paying for?
