stillware/ImgFetch ? reverse-engineered prompt

Build me a privacy friendly Chrome and Edge extension that helps people save images and screenshots from any web page.

I want it to let me scan a page, preview all the images it finds, and download one or many at once. It should grab the best working image source when possible, let me save images in formats like PNG, JPG, and WebP, and optionally bundle a selection into a ZIP. I also want a screenshot tool that can capture the full page, the visible area, a selected area, or a single element.

After taking a screenshot, I should be able to mark it up with simple tools like pen, arrows, shapes, text, pixel blur, crop it, undo mistakes, copy it, or save it. Keep the whole thing fast and simple, with a clean popup and settings page. No accounts, no tracking, everything works locally on the device. If you need to check current browser extension docs or limitations, look them up online first.
