I followed the below directions untill I got to: Modify->. But under that menu, "transparent Color" doesn't exist.
This is Version 9 ot the program. Anyone have experience with this?
1.Open or create the image you wish to add transparency to. Now, use the Eye Dropper tool to select the color from your image which will be used for the transparency (do this by right clicking on the portion of your image where the particular color is located).
Now, press CRTL+A to select all and then choose Selections->Modify->Transparent Color and set it to Background color and Tolerance 0.
Now go to Color->Decrease Color Depth->256 Colors and use the settings below:
1)Optimized Median Cut
and click OK.
Next, go to Colors->Set Palette Transparency... see below and click ok (if you want to test the transparency, click the proof button).
