looking at a few recent threads I can't see this problem - it seems to say 'image' in the threads I've looked at
If you do spot general problems the best thing to do is send a PM to the site administrator StuartDH or to one of the mods (myself, glsammy, Oy, fungiJohn, Fourwings). If the problem relates to a specific thread you should simply report the thread by clicking on the exclamation mark at the top right of each post.
