Binary files & Tmp directory

Hope someone can give me a pointer as to why this script keeps failing with the error message below. It's designed to take data from an upload form (images) and post them into a mySQL database. If you need more info I have it but thought I'd see if there was something wrong with the script first. I have my database table created, I have the result query working just peachie but actually getting any images into the database has me stumped. Wondered if it is a read/write permissions thing? I have no access to change php.ini options on my ISPeeez server. php info returned this information on the tmp directory, can I set this myself somehow if it is read/write that is the problem? upload_tmp_dir no value Thanks in advance.
