Fay - can't you just do it in Pshop... Image/Image Size then select 200 for width & change to percent (think default is pixels). Make sure Bicubic & constrain proportion are ticked then hit resample.....

I would stack the R,G,B at the 2x2 size then resample them before creating the RGB & layering with L (assuming that is what you are trying to do)

i did that, but Maxim only shows a tiny image in the middle of the RG or B sub. I opened them in Maxim to Align

Fay make sure you do 200% & not 200 Pixels....

John, my head is done in! Can't get it to work!!!!!!!! I have tried all programs & cannot get it to work. Tried it with blue, I either get a a sub with nothing on it or it has a minute speck in the middle of blackness!!

Fay - Just email me one of the stacked fits - either RGB & I will do it & send back..
