I wrote a PHP script a few months back which basically acts as a simple image uploading service. It always worked fine, until I switched to DreamHost, so I'm guessing it's something different with the configuration.
Basically, with this HTML form:
The PHP script does not work because the temporary file is not being created on the server. I get the following error message:
unable to create a temporary file in Unknown on line 0
Thanks in advance.
