Does your solution look for some .ashx file at the root? I am getting lots of errors from server when I try to view files via your tool. It shows square placeholder for thumbnails but doesnt show thumbnails.
Below is the error message-
Error in:
http://aolmi.org/IZWebFileManagerThumbnailHandler.ashx?/custom/nl/standard_images/yellow_picture5.jpg
Error Message:
The file '/IZWebFileManagerThumbnailHandler.ashx' does not exist.
