This method seems sound in my experience, but my issue was solved more simply and swiftly. But, on the other hand, it's always a good idea to backup often regardless.
How my Image browser fault was corrected, run a full phone backup befor proceeding:
1. Connent phone to pc via usb cable.
2. When prompted on the phone's screen, select a 'Mass storage' connection type.
3. Running a vista operating system you should be prompted to scan and fix file system errors. Select the recommended option of a complete scan and fix, including recovery of bad sectors.
4. When fix is complete, disconnect after running a 'Safely remove'.
5. Problem solved.
So this is how it's done if you have a vista pc. I can only guess this solution will work similarly with an xp pc or any other file system correcting application.
