[Zope] IO Error Broken Pipe with Photo Product

[complaw@hal-pc.org]

I'm using the Photo product on the FreeZope site (http://www.freezope.org/). 
I've loaded many photos onto the web site, but yesterday and today I am unable
to upload photos.  Instead, I receive the following error message:

Site Error

An error was encountered while publishing this resource.

IOError
Sorry, a site error occurred.

IOError: [Errno 32] Broken pipe



This problem exists on multiple boxes (running either Linux or Windows 2000)
that are on SEPARATE networks.  The files themselves are fine, being read with a
variety of software applications, including Konqueror and Mozilla.

Any idea what the problem might be so that I can pass that along to the FreeZope
people?

Thanks in advance,

Ron
