[Gimp-user] I have a question about the Colors tabe

[cinque8 <forums gimpusers com>]

Hello,

I entered a photo into Gimp in both jpeg and png format. I then clicked on the
Colors tab, and was going to click on Color to Alpha, but it was not highlighted
for use. What do I need to do in order to use the Color to Alpha tab?

Thank you
