Just follow these very easy steps
Click on "New Discussion
Click on the icon that looks like an envelope with a stamp
Click on my computer (if thats where you have the photo or clipart saved)
When you find the photo or clipart click on "OPEN"
Click on "ADD PHOTO"
Click on "SEND"
Also if you want to add a pic or clipart from another of your groups you have listed or from my group of clip arts just click on the room name, it will show you a list of albums just click on clip art and it will bring up all the cliparts in that album just click on what you want to add, (you can add more than one at a time) then click on add photo.
Same applies for adding clipart from the clipart gallery
Hope this helps
