Quickly used your code to get the image for you, Ashley!
That's what appears when I used the code you gave me.
For comparison's sake, the coding I used was:
<center><div><center><p style="font-family:trebuchet ms;font-size:18"><b>~welcome to fan clubs & groups~</b></p></center></div>
<div><center><p style="font-family:trebuchet ms;font-size:11"><b>the place where fandoms, common interests, and supporters find each other~</b></p></center></div>
<div> </div>
<div><center><img height="288" src="https://24.media.tumblr.com/5602657e1d7b43b805153fbede4040b6/tumblr_muqsbs1VO11soalt8o3_500.gif" width="500"></center></div>
<div><center><p style="font-family:trebuchet ms;font-size:13"> </p></center></div>
<center><div><b>Reminder: Please visit <a href="http://www.pokecommunity.com/forumdisplay.php?f=24">Pokemon Clubs</a> for Pokemon-related groups!</b></div></center>
