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"
