Unable to Sync iPhone and Unable to Sync Photos to iPhone

Another issue I found moving my iTunes and iPhone to a new PC, was Sync'ing was hanging, though I did have my Apps, Podcasts, and Music. Upon further investigation, I discovered that if I did not sync my photos, then it no longer got stuck.

First I was thinking it was a permission issue with Windows 7 -- but I made no progress. I finally figured out how to solve the issue.

1. Stop the sync'ing
2. Delete the iPod Photo Cache in my photo folder(s)
3. Resync

I can only assume the iPod Photo Cache had pointers to the location of my photos on my old computer.
