My pictures won't work
 

I had no problems putting my venus flytrap into my signature but everytime I try to put anything else in it doesn't show up. I put all of my pictures into ImageShack, including my flytrap but for some reason, none of the other images will show up when put into my signature. Could I be doing something wrong? Why couldn't the LimeWire Forum have the option of uploading pictures from your computer into the signature? It would be easier then using the IMG codes.
