Newbie Notes: “Index” Mode
Have you ever come across images that you can’t seem to edit, copy or move to another document? And when you look at the layer, it says Index instead of Background? Many clipart images are like this. Having accumulated lots of Public Domain pieces of clipart when I first started to get interested in digital designing, I found it very frustrating not to be able to use them! A simple workaround is to drag a selection box around the whole image and then you can move it into your document. I am indebted to some kind person who answered my plea for help in one of the Forums several years ago and I’m terribly sorry I can’t remember which one! Since then, I have discovered that these files are saved in Indexed Color Mode and you can simply change this by going to Image – Mode – RGB, and then you can carry on as normal. However, saving your converted image as a jpg at maximum quality usually at least doubles the file size, so I keep my originals in their Index mode to save space.
