1) A way to set some kind of tolerance threshold for "similarness". A lot of the time I want an image exactly the same as what I'm searching for, except a different size, in colour, etc. When I search for the biggest image I often get a lot of images with borders, additional whitespace, etc... Any chance of adding more options to filter results?
2) When searching for largest image, if there are multiple results with the same dimensions, they aren't ordered by file size. So you can have two 1024x768 results and the 100KB one will appear before the 300KB one. Generally when searching for the "Biggest" image you want the highest quality one.
Following on from this, maybe tweak the algorithm to put a 1024x768 400KB image ahead of a 1066x800 80KB image.
3) When searching for images, make "Your Image" an actual link back to the original image. Its a real pain when using TinEye to have to keep the tab with the original image open just because you might not get the results you want.
4) An option for the plugin to let it open searches in the same tab. Most of the time I want searches in a new tab, but sometimes it'd be really handy to disable that behaviour. In tandem with (3) it could streamline finding better quality copies of images.
5) Maybe writing in the FAQ about some good uses for TinEye and tips for getting the results you want. Apart from the obvious "find better quality/original versions of images" the idea in the eBay thread was a really good one. I personally used TinEye a lot in an art project I did recently. I say this because TinEye isn't really a normal search engine so how to use it effectively isn't as obvious as say with a text-based search engine.
6) Let the plugin search file:/// URLs. Or is this impossible due to JavaScript security?
