Image Dif calculates those differences at pixel level or region level.

Firefox extension that replaces images on websites with images you select from your local computer An extension born as a request from my friends Goofy and Efdur from babelzilla.org, My Image Here allows you to replace an image on a website by selecting an image from your own computer.
All replaced image references are stored in the new Firefox 2.0 SQLLite storage implementation, and will therefore remain replaced untill you remove the reference again. So you can clear your cache, restart Firefox, etc. without losing the pictures you had replaced.
I am not yet sure as to how usefull this extension will actually be for you all, but just have a look. My Image Here was initially intended for web developers only, but after releasing it on babelzilla it appeared to be great fun to just play with it as well.
How do I use it? Well, you just right click on any image on a website (as long as it is a html IMG element), and select [Load My Image Here...] from the My Image Here context menu, and select the image you want to see instead of the current image, easy as that.
Main features:
- Replace the image as it is on the website, or force your image to be the same size as the original image.
- All My Image Here data is stored in the new Firefox 2 SQLLite storage system.
- Export and Import My Image Here files so you can share your customized websites with your friends.
- Available in: en-US, fr-FR, it-IT, hr-HR, de-DE, id-ID, nl-NL, pt-BR, ru-RU, uk-UA, zh-TW, da-DK, es-ES, ja-JP, sk-SK, hu-HU, ko-KR, tr-TR, zh-CN
System requirements:
- Firefox 2.0 - 3.0a1

The Windows Imaging Component supports discovery of new and proprietary (e.g., Raw) image formats. Any application that uses WIC can take advantage of new image formats as soon as their CODECs (encoder/decoders) are installed on the PC.
WIC includes updated CODECs for TIFF, JPEG, GIF, PNG, & BMP that are much more secure than previously released CODECs for these formats, and also supports a new high-performance image format called Windows Media Photo.
Additionally, WIC provides metadata readers and writers for common image metadata formats, and enables applications to preserve their own metadata inside image files so they dont need to create "sidecar files".
