Thanks , Nikita .
I have not a good editor like Photoshop .
I tried with Gimp , Paint net , Photo pros pro and XnView only .
I was going to try Irfan view but it only reads them (SGI) like XnView .
I could not make a 256 color SGI image .
Edit : SGI doesn't support it , if i understand correct (it says obsolete ) .
But TG2 could read a normal RGB SGI image . But this doesn't help me of course .
I have a feeling TG2 treats 256 color images as greyscale . But i don't know of course .
Did anyone tried it with 256 color images in TG2 ?
