Thread:Project:Support desk/Filename Case Sensitivity Question

I have a small problem I'd like to solve. While the Uploads page of a default installation of MediaWiki sees (for example) RedMoon1.jpg and RedMoon1.JPG as the same thing, a command line Image:RedMoon1.jpg won't work if the file was uploaded as RedMoon1.JPG.

Is there a way to turn off case sensitivity for file names? I know there's $wgCapitalLinks, but that seems to be a different issue from this.
