API2 image upload returning empty response

Hello, I have a few images that will not load into Razuna using API2 and a custom application. Other images will load just fine, and I can’t find any rhyme or reason as to why a handful of others are not. For the images not loading, I’m getting an empty response, no error code, no message, etc… Does the api create any sort of log that I can look at to try and troubleshoot the image files that will not load?

Our Wiki page http://wiki.razuna.com/display/ecp/Upload+API2 tells you how
to debug your upload. Also, since this is your custom app there is little
we can do other than telling to make sure that you are posting valid data,
especially the file itself, to the API.
