I have tried the software that Howard linked you too. I didnt really care for it myself. Remember all of the ones that say they are shareware only give you like 5 minutes of trial before it stops and wants you to buy a license. I am still searching for an program to use myself. Can't recommend a thing at the moment.
As for pictures on your Zune. Its very simple to copy them from the PC. After you have downloaded the software on the PC. You will see 3 little icons in the upper left side of the screen. One for music, one for pictures and one for video. Click on the pictures icon. You can search from there for pictures on you PC, CD, jump drive etc. Copy them into your library (same way you do audio) first. Then drag and drop them on the right side of the screen where it shows how much space is available on your Zune. Then press the SYNC buttom towards the bottom right of the screen.
Hope this helps....
