What is an index layer? How can I change it so it isn't an index layer? I pasted an image from the internet, and I can't add any more layers.

The color mode of your document is set to "Indexed Color." Choose Image>Mode>RGB to get back to a color mode that supports layers.

GIF files are indexed color files. It's likely you copy and pasted a GIF or PNG8 file into Photoshop.
