* Description
//================================================================================
:- phUploader is a script for uploading single or multiple images or files to your website. You can specify your 
:- own file extensions that are accepted, the file size and naming options. This script was built and tested on 
:- IIS6/7 and Apache 2+. It's recommended to use php 5.1+ This script is very useful for temporary file
:- storage or simple sig and avatar hosting.
//================================================================================
* Setup
//================================================================================
:- To setup this script, upload phUploader.php to a folder on your server. Create a new folder named uploads
:- and chmod it to 777. Edit the variables below to change how the script acts. Please read the notes if you
:- don't understand something.

//================================================================================
* Frequently Asked Questions
//================================================================================
:- Q1: I always get an error that the files were not uploaded. IE: GENERAL ERROR
:-		1) Make sure you have CHMOD your "uploads" folder to 777 using your FTP client or similar. If you do
:-			 not know how to do this ask your hosting provider.
:-		2) Make sure the uploads folder actually exists. This is the second most common mistake aside from
:-			 improper permissions.
:-		3) If you are having problems uploading after you have chmod the uploads folder 777, try using the
:-			 full server path in $fullpath below. If you do not know this ask your host.
:-		4) Make sure "file_uploads" is set to ON in php.ini
:-
:- Q2: The page takes long to load and then gives me a page cannot be displayed or a blank page.
:-		1) This is usually due to a low value in php.ini for "max_execution_time". 
:-		2) A newer ini setting "max_file_uploads" in php 5.2.12 was added which may be limiting the number
			of simultaneous uploads.
:-		3) Your "upload_max_filesize" and "post_max_size" in php.ini might be set to low.
:-
:- Q3: How do I edit the colors of the form?
:-		1) You will need to edit the CSS near the bottom of the script to change the looks and colors of the form.
:-			Check http://www.w3schools.com/css/default.asp for more information on CSS.
:-
:- Q4: Can I remove your copyright link?
:-		1) I can't physically stop you. However, I really appreciate it when people leave it intact.
:-			Some people donate $5, $10, $20 to take it off.
:-
:- Q5: You never respond to my emails or to my questions in your forums!
:-		1) I'm a very busy guy. I'm out of town a lot, and at any given time I have several projects going on.
:-			I get a lot of emails about this script, not to mention my other ones.
:-		2) I only understand English. If your English is very bad please write in your native language and then
:-			translate it to English using <http://babelfish.altavista.com/babelfish/tr>.
:-		3) If you are going to contact me, describe the issue you are having as completly as possible.
:-			"dude me form don't work see it at blah.com what's wrong??!?!" will get no response, ever. Write
:-			in detail what the problem is. Spend a minute on it, and maybe I'll take some of my time to reply.
