For those who don't have the HTML manual for mtPaint installed, we have a copy of it online:richard.a wrote:I've created an almost reasonable one for gaim from an existing coloured icon - but I can't seem to find a way to convert an existing image with a solid white background to transparent. There seems to be no help file with mtPaint. So I need a brief tutorial please

As for transparency - if you want to make a single colour transparent, it's manual section 3.3.5 "The Transparent Colour"; if you want alpha channel, it's section 7.5.1 "Converting a Colour Transparency to an Alpha Transparency".
