I have recently opened some images, and in the layers pallete; instead of saying "background" it says "Index" I have been unable to figure out why it says "index" and cannot do anything to image because every tool is greyed out. Whats up....I must be doing somthing wrong.
Thank you all in advance for any information

"Index" is a reduced gamut or colour range. The palette consists of only the colours used in the image. This cuts down file size.

To use these images you first have to convert them from Index to RGB.

Simply go to Image > Mode > RGB.

All tools and filters will now be available.
