There is something wrong with the wiki's thumbnail images. Thumbnails of some existing/old images as well as newly loaded images are missing.
For instance, when I upload a pic, the thumbnail is missing on the load result page, http://electricvehiclewiki.com/File:Nis ... e15_sm.jpg. The thumbnail's URL is http://electricvehiclewiki.com/images/t ... e12_sm.jpg.
The image _IS_ there, however e.g. http://electricvehiclewiki.com/images/9 ... e12_sm.jpg
Here's an example of an existing image that DOES have a working thumbnail:
Pic: http://electricvehiclewiki.com/images/9 ... .58.21.jpg
Thumbnail: http://electricvehiclewiki.com/images/t ... .58.21.jpg
