Hipstamatic and PhotoShake Photos Transfer as Blank Page Icons (But are viewable)

I noticed that the photos I have that were taken with apps like Hipstamatic and PhotoShake are transferring over as blank page icons. They do open up properly and are viewable, so it's not that big of a deal; mostly just cosmetic. I'm just wondering if there is a way for me to turn the blank page icon into a thumbnail of the photo. When I view the properties of the photo, the File Type is listed as "File" instead of "JPEG."

Note: I'm transferring from iPhone 4 to PC Windows 7.

Anyway, aside from this tiny thing, the app is super convenient and fast.

Thank you!
