It would be great if Picaloader had the ability to check at least jpg files to see if they were corrupt and then display them in the search results tab. Then the user could review them and check the refferer url to see if they were corrupt on the website. If they were OK on the website, it would be nice to then have the ability to tag them and redownload them over writing the bad files.
I have found some corrupt images on my harddrive but not many and they might be bad on the website. I have also seen files that check out OK but the image is definately bad but, it's also bad on the website!
