iPhone photos problem (iP5, iOS7)

[pkson]

Hi guys. I'm in a serious pickle here.

Last night I copied all my 2013 photos from my iPhone 5 (32GB) to an external HDD through DiskAid.

I proceeded to delete all the 2013 photos from my iPhone.

I checked what I had left, and I had all the 2014 photos and videos still in my photos.

Or so I thought.

It's really really strange, and I'm too scared to touch anything at the moment, but here's what my phone is showing/doing.

- If I go to the Photos app, all I get is.. a bunch of blank(?) video thumbnails, and only a couple of photos.
- The app usage info in the phone says I have 1.3 GB of memory usage. Not sure if that's the amount of residual videos I have left on the phone, but probably mostly Photostream.
- If I plug the phone in iTunes, it says I have 7.8GB worth of photos and 1300 files. (Which is similar to what I thought was remaining in the phone last night)
- DiskAid can't find anything else.
- iTunes says the phone's empty storage space is currently at 14GB which coincides with what I had last night.
- DiskAid says it's at 15GB.

I really need a way to access the 6-7GB of recent photos.

Can anybody help? Any suggestions?

Thanks in advance.
