there are some things you could do before being sure the iPad needs repair
1, Try on another computer. If you're able to import photos on another computer. In that case, you could try removing and reinstalling iTunes and its components using http://support.apple.com/kb/ht1925 for windows XP or http://support.apple.com/kb/HT1923 for windows Vista or windows 7.
2. Try using another cable
3. If you're not able to import photos on another computer and another cable, the device may need service
Hope this helps

Another way. You can use a USB flash drive & the camera connection kit.
Plug the USB flash drive (works the same with an SD card) 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.)
