Be an Oyster for Autism!

i'm trying to add the tagless shirts to my website, and I'm using Gimp to change the colors on the line drawings and it's not changing the colors right... pink turns to tan and green to grey... like there is some filter on the colors when I try to change them.  Man alive!  I need to make peace with computers!!  listen computer.... i like you... ok, ok, I LOVE YOU, OK?  Really, I love you and think you're marvelous.  You do amazing things and you are a wonderful tool and I LOVE YOU and appreciate your brilliance... wonderful, wonderful machine with all of your wonderful programs and applications.  you are fantastic!  hmmm..... maybe that's better.  I'll begin again...  :)
