Is it possible to set multiple colours as transparent on one image? Or, should I just change each of the colours I want transparent into one colour?

Not unless you convert the image to a memblock and test the colour of each pixel and change it to transparent if required, then change the memblock back to an image.

If you don't have a lot of images it will proberly be quicker just to use your image editor to change all the transparant areas to one colour.

Well, I am doing this with user-chosen images (this is an image view utility), so I will have to chose the hard way. Thanks
