dessant/search-by-image — reverse-engineered prompt

Build me a browser extension called Search by Image that lets people do reverse image searches really easily in Chrome, Firefox, Edge, Opera, and Safari.

I want it to work from the right click menu and the toolbar, with settings where I can turn search engines on or off and reorder them. It should support lots of reverse image search engines, around 30 plus, and let me choose how the search happens depending on the situation. The main ways I want are selecting an image on the page by URL, uploading the actual image file from the page for sites that block direct links, capturing part of the page, picking an image from my device, pasting from the clipboard, and searching from an image URL.

It should be useful for things like fact checking, finding copied photos, and shopping for similar products. Please make the options and general UI clean and simple, and make sure it works well with images embedded in different ways on a page. Look up current browser extension docs online if you need to.
