Q: how do i up load photos from my pc to ipad

You either:

Sync them to the iPad via iTunes, or

Upload them to a Photo Stream using "iCloud Control Panel" software, or

Use a 3rd party app to transfer them to the iPad over Wi-Fi, or

Use a camera connector kit to transfer them via SD card or USB

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.)

Just drag them or copy and paste them to Dropbox on computer. It will be waiting for you when you open Dropbox on iPad.
