i re-bolted up the freeimage support since i needed to read more formats it 
works ok as far as i can tell no issues yet.

you need to add a flag for palette index 0 meaning transparent though.

how would you implement it

( i hacked it horrifically in by passing it along the whole image load API 
chain 
since i couldn't access any options blocks from inside the image load code 
easily )

If i was given some hints on a best way o implement the passing down i will 
submit a 
patch for it.

Also passing on the binary alpha ( and alpha ref ) to free image is useful

I'm not sure what you mean. Paletted images should be converted to RGBA at load 
time. Why don't you simply set the alpha to 0 at load time? How do you 
determine whether 
palette index 0 is supposed to be used for transparency or not?
