bitmap gamma

Hi all.

I have a script that is loading in some bitmaps as thumbnails. The only problem is they are displaying with their gamma as 1. I renderedn them in a file with gamma setup as 2.2

is there a way i can change the gamma value when the script loads the image in? Of will i just have to render the iamges "overbright" to compensate?

something like this

bitmap foo "Bitmap" pos:[60,60] width:200 height:150 fileName:"//harddrive2/temp/Max/Chrome_1_Prev.jpg" gamma:2.2

If that doesn't make sense please let me know!
