On your phone, open the gallery app and see if any photos are there. If you don't see anything, then let's see if they just aren't being displayed. You should have an app called "files" or "My Files" or something like that to browse the phone's file structure. If you can't find one of those, please download a file manager like
Astro. You need to look in /sdcard/DCIM/camera/ which is the default location for the photos taken with the phone's camera.
On a PC sign in to your
Google Account ... the one the phone was registered to. Once logged in, in the upper right corner you'll see an icon for google apps, nine squares. Click on that and find "photos" on the list. If you had your pictures set to sync, you'll find them there. If there is nothing there, then I'm afraid your photos are lost.
