";Why can't I upload my file / image?
 * I've been editing on the wiki for a while: This usually occurs if your filename is too generic or was automatically generated by another program. Rename your file to something that accurately describes your file before upload.
 * I'm new to the wiki: New wiki editors have restricted permissions on the wiki, including uploading images. Please have patience; as you continue editing these restrictions will be lifted."

Hope this helps.
