photos disappear from gallery after renaming

[hawkeyes2002]

I snapped a few photos on my galaxy nexus (root, 4.0.4) that I wanted to attach to an email. The phone of course automatically gave them a numerical name ('IMG_numbers_numbers') but for this email it was important that I give them 'real' names.

The easiest way I knew of to rename the photos was to use Root Explorer. I changed the names of the photos in '/mnt/sdcard/DCIM/camera' but it also automatically renamed them in 'data/media/DCIM/camera' as well.

After I renamed the photos they disappeared from the stock Gallery app - they just show up as empty black squares. I cleared data and cache from the Gallery app but that didn't help.

Does anyone know how I can get the photos to show up in the Gallery app again?

How should I rename photos in the future so that this doesn't happen again?

Should I just get a different Gallery app?

Thanks for any help help.

You must have deleted the extension at the end of the name of the pictures. There should be a .PNG or .JPG attached at the end of the pictures names.

Sorry - should have been clearer. The files do have the extension (.jpg). I can still get to the photos through Root Explorer, so they're still saved on the phone. I just can't see them in the stock Gallery app, which also means they don't show up in my Google+ account.
