In whatever program you are using for the image, try using 'Save As' and make it a jpg, gif (or whatever) accepted file type.

Some screen capture softwares default to saving as a bitmap (BMP), but I don't think I've won't seen one that won't allow "Save As' a jpg file .. then you can use the mentioned feature


Make your sound your own!
