Trying to get images to show up when adding html tag into description

[unitedgaming]

I am adding the image in the channel manager like this:
------------------------
Some decription of this channel! blah blah


<img src=http://i.imgur.com/blah.gif border="0" >

rest of description blah

---------------------

Someone else on our site who is not around right now did the same thing on another channel and it works. When i do it it replaces the < and the " with the URL replacements. Is there a way i have to escape them or somethings

&lt;img src= http://i.imgur.com/blah.gif border=&quot;0&quot; &gt;

I have a very small amount of programming knowledge with html
