We have a set of documents that are not showing up properly, and we get a "Failed to Load Image. Unknown image format. [6604]" error in the Laserfiche client, and "Lfi_LoadImage of a file failed." in the webclient. 

The source files were fine, and the majority of the files from the batch that was imported worked fine.  I need a way to identify which files are having this issue, so we can replace them as needed.  Is there a way to get a report on files that do not have images?
