leeenfielf,

You need to actually select an actual graphics file. They generally end with .jpg or .gif . The other filenames are often actually web references, and possibly have "commands" in the address line. If so, sometimes editing the web address to remove the stuff after the .gif or .jpg sometimes works.

Generally right clicking on an image and selecting properties or view image info can reveal the image web address. Or selecting "copy image location" as in firefox.
