That's why we need a naming policy. How can you expect to search for an image of Optimus Prime if the file you want is a random string generated by Tumblr or a date and time generated by vlc media player?

Name them properly then you can search for them easily. The name summarizes what's in the picture and where it is from. The file page itself states where its from fully i.e. a source and a description of what's in the image
