Mike, you need to make sure the directory "tmp" exists in the root of the 
directory where you installed XEP. In your case it looks like this is 
/usr/java/XEP/3.8. Ideally XEP should be capable of creating this directory 
itself, but it doesnt. In 4.x image retrieval works very differently and 
temporary files dont appear to be required.
