Any idea why a image in this directory will not display correctly?
http://Mysite/MyWiki/images/thumb/8/86/Map_of_US_TX.svg/200px-Map_of_US_
TX.svg.png
But this directory works just fine:
http://Mysite/MyWiki/images/thumb/8/86/Map_of_US_TX/200px-Map_of_US_TX.s
vg.png
See the missing .svg in the directory name "Map_of_US_TX.svg"
