Some things to check.

1. Write Permission on the /Content/Images/ directory and it's subdirectories
2. Your host has given you enough disk space to hold the images.. if it runs out and a write is denied, you'll get a save failure like that.
3. Lastly, if 1 and 2 are fine, try investigate the individual images for those products, not read-only, writable, etc.
