Stellar Phoenix JPEG Repair stood out straight away thanks to its dedicated thumbnail extractor. Point this at your corrupted images and the program will do its best to extract any thumbnails they might contain; these plainly aren't going to be high resolution, but if they're the only record you have of the image then you'll probably still be very happy to see them. And the feature's inclusion here is a great idea. Of course the program can also try to repair your JPEGs, though, and here it works more or less exactly as you'd expect. Add a few files, click the 'Repair' button, and wait a while for the results to appear - it's all very straightforward. The program's repair tools were mostly very successful, too. Our zeroed signature images were recovered immediately, for instance. The 'corrupt header' set was more difficult, but Stellar Phoenix still restored 12 out of 14.
