Sadly it is much bigger than 32 pixels, not entirely possible to even condense it down, could perhaps spilt the graphic up into 32x32 blocks!
Not tried a copper UI overlay, possibly needing a free spot on the palette for this to which could be a problem.
Actually thought there might have been a simple way that Id missed but am somewhat relieved that its not just me. If no solution via code then perhaps divert the text to a panel, not elegant for sure.
Bet earok loves us coming up with more issues than solutions
edit: Was typing this as you typed a workaround, thanks UltraNarwhal, will give that a try and see how it works out, much appreciated!
