My webhost will not allow extensions but I need to make an upload progress meter. Is it possible without extensions. If you know of any methods your input would be greatly appreciated. Thanks in advance.

The only way to make a pure PHP & Javascript/jQuery upload progress bar is by using APC or UploadProgress PECL module. Check your phpinfo() to see if either of them are installed. If not you'll have to use a flash/jQuery solution like Uploadify
