Forget about syncing the pictures, use a 3rd party app like Photo Transfer App. It's a lot easier and less risk of deleting things off your iPad.
It's also easier to delete your photos later.
Another way. You can use a USB flash drive & the camera connection kit.
Plug the USB flash drive into your computer & create a new folder titled DCIM. Then put your movie/photo files into the folder. The files must have a filename with exactly 8 characters long (no spaces) plus the file extension (i.e., my-movie.mov; DSCN0164.jpg).
Now plug the flash drive into the iPad using the camera connection kit. Open the Photos app, the movie/photo files should appear & you can import. (You can not export using the camera connection kit.)

iPad User Guide for iOS 5
Okay, first question...what is the Camera Connection Kit? The only thing in my box was the USB cord (is this the Camera Connection Kit?) and the wall charger...guess not! I was watching the video and I guess that means more money and I cannot afford that right now...:(
I did download the User Guide the very first day so that I would have it all the time and some of it just confused me. Before I joined the community here, I was asking questions of some friends that have iPads, iPods, and other Apple products. One of them steered me here because I was waiting sometimes all day for answers...which was no real big deal since I work from home and could check in often. Problem with a community like this is that if I get busy with work and cannot check in for awhile then I lose my place! LOL
