There are two options you can use at Gomotes. You can choose out of UBB and HTML.
Click the gomote you want to use. In the emoticon toolbox you found now the two opitions.

UBB is used in most message borads, but noticed, not every board admin allowed to link external graphics. So be sure if it is allowed, to link external graphics. Take a look in the FAQ or asked the admin of the board.
HTML is for your personal sites or blogs. Just add the code to the place where you want to use the gomote.
If you know which code you want to use. You should first mark the whole code. Use the right mouse and click in the codefield. Choose mark all.

Now the code should be marked. Click again with the right mouse on the marked code and choose copy. Or use the keys ctrl and c (windows) or cmd and c (apple).

If you’ve done this. Go to the place where you want to use the code. Click again the right mouse and choose paste. Now the code should apply on this place. Or use the keys ctrl and v (windows) or cmd and v (apple)
