Magic words such as {{FILEWIDTH}}, {{FILEHEIGHT}}, {{FILESIZE}}, {{FILEEXTENSION}} would be helpful to me. I want to categorize files on commons based on these values.
For example, I want to be able to be able to determine if an images resolution (height x width) is within a certain threshold. Likewise I want to be able to determine if the image is widescreen or not.
I would also like to check the filesize is reasonable so that it isn't too large or perhaps too small.
I also want to know the file extension so as to be able to eliminate file-types such as "pdf", "svg", "ogg", "ogv" and etc when trying to compile a list of files that may be worthy for desktop backgrounds.
I could achieve all of these and more if I had such magic words. The information I seek is present on file description pages already though I am unsure how those are generated.
