Hi all & Julie, I really don't wan't to sound stupid but!! Help please

I tried to put some stuff to show in on my blog like you told me but for some reason I got nothing. I don't know if the area you were telling about was the same place I was tring it at or not but when I clicked on the gray area I got nothing. I then picked a picture up out of my pictures but it would not let me paste it even after I checked the view source box. Could you or someone run this by me again of were I need to get my picture at. Thanks Rob
