I am using Photoshop CS and I am trying to do a fill solid colour to a background of #dcdcdc. This is not a problem.
I then change the opacity to 70% so i can just see the transparent background. Not a problem.
i then go to save it as a .GIF or Save for Web then when it comes to it the colour is now solid again, even when the transparency check box is checked.
Any help much appreciated.
