great, did exactly what I needed.
one annoyance was that it kept slapping the "logout" button of the website I was into, so I removed it with the DOM inspector, and that problem stopped.

another problem was that all the images had the same name. Fortunately there's a "rename everything" button but I didn't realize I had to slap it. ideally the extension wouldn't overwrite images by default.

but it saved me a ton of clicks, so thank you!
