How
I make a banner:
First you need to have a thing on photobucket.com. If you don't have one, then make one... THen you have to get a picture from google or photobucket or somewhere like that. Right-click on the picture and save. After which you can edit it (using some kind of photoshop or paint). Once you've done that, save it again. Then go to photobucket and add it on there. After which you place it on gaia in the form of:
and then you put it in code form below the picture:
the button that says code above your post thingy
((there are, of course, other ways but this is how I do it.))
