[Gimp-user] Colour Profiles, RGB and convert to PNG

[Richard Brown <rich gucu org uk>]

Hi All

I am trying to convert a jpg to png. I want to remove the background 
colour. My usual method of doing this to Colour to Alpha but the 
selection is greyed out. When I open the jpg it asks me whether I want 
to convert to RGB working space. It has a colour profile embedded in. Is 
it possible to remove this or convert the image to png in a different 
way please? Thanks
