You could make a reference coded into the metadata that refers back to the image file. When the image file is altered, the metadata notes this change. I.E. history. Then, the individual pages note that the image had its name changed. Like an inlined redirect, if you will. Eliminate the redirect page created by the name change and instead in-line the redirect.
