Depends which part of the file gets corrupted, and the issues between PNG and JPG are dramatically different. There are key bytes in the file (like size of segment, start of segment, etc) that if corrupted would dramatically mess up your image. If it's just in the compressed image data you'll just see some artifacts, and a JPEG already has plenty of compression artifacts anyhow...
