Thanks man!
I think the code i was using was for leaguecraft or something.

Hello! this is a pretty good guide put I seen you had some trouble getting pictures into your guide

If you want to make a picture of the item or spell type it like this:

[ icon=frozen mallet size=35 ] <---- remember no space between brackets =P

and it will look like this

changing the size will make it bigger or smaller also, hope I helped!
