All the other albums do sync to the PC, but it is a one way sync, strictly from the PC to the iPad. They don't even sync with iTunes, but to folders specified.
The camera roll, or on older iPads the Saved Pictures album are unique. iTunes does not sync it, though it does include the folder in the backup so that they can be restored.
You can use the email function in the Photo app to copy up to five photos at a time. Many other apps, such as the Facebook app, can access the photos to upload or use in other ways.
As MadDragon said, if you are on a PC the device should show up as a drive on your computer, just like a USB drive would. You'll find the pictures in the DCIM folder.
On a Mac, you can open iPhotos and the iPad's Saved Pictures will show up under the devices list.
Or you could use the iPhone Explorer program on your computer, Mac or PC. You'll find the files under Media in the DCIM folder. It is safe enough to copy files off the device this way, but
I don't recommend adding or deleting files from the device unless you know exactly what you are doing.
