the picture you want to use has to be on web space or from something u have found on the internet...
right click on the picture and go to propeties at the bottom of the box...then highlight the URL address and copy it
then go into the user control panel and then into edit profile...paste the address into the signature box...
then u have to put the image thingy round it to make it work,
it looks like this(but remember to leave out the spaces or it won't work)....
[ I M G ] the address of your picture [ / I M G ] ...i put it in red so it stands out more.
click on submit modifications and then it should work
if it doesn't i'm sure some1 will be able to help...i think i might have explained it a bit crappy but if it helps then it's a first for me
