make your image (or use one of my premade ones) and upload it to tinypic/photobucket/etc. if you're using one of mine i've already done this for you (the code underneath the image)

first you're going to want to link the image to your profile, so that when it is posted in a bulletin and you click it, it will go to your profile (or where ever it is you want it to go)

so say this is my image

i upload it to photobucket and take the direct link, or this  :

http://i290.photobucket.com/albums/ll274/fashionablylatelayouts/supportcodes/support1.png

then here is how you link it

<a href="YOUR URL HERE"><img src="DIRECT LINK TO IMAGE HERE"></a>

so for example, mine would look like this

<a href="http://www.fl-lyts.com"><img src="http://i290.photobucket.com/albums/ll274/fashionablylatelayouts/supportcodes/suppor
t1.png"></a>

^^ that will link it to your profile. for example: click this

usually, i will center the code so that its in the center of the bulletin. heres how the code would look if you were to do that.

<center><a href="YOUR LINK HERE"><img src="DIRECT LINK TO IMAGE HERE"></a></center>

or mine, for example

<center><a href="http://www.fl-lyts.com"><img src="http://i290.photobucket.com/albums/ll274/fashionablylatelayouts/supportcodes/supp
ort1.png"></a></center>

and thats the whole code!

now you want to put it in a little textarea on your profile, right? well thats SUPER easy. just take your code and put textarea tags around it. for example:

<textarea><center><a href="YOUR LINK HERE"><img src="DIRECT LINK TO IMAGE HERE"></a></center></textarea>

that will look like this:

 <center><a href="YOUR LINK HERE"><img src="DIRECT LINK TO IMAGE HERE"></a></center>
