PHAkT v1.0: org/gjt/mysql/Driver - Class Not Found

With PHAkT v1.0 some users are getting the following error when trying to create database connections :-

org/gjt/mysql/Driver - Class Not Found 

This is happening because of the new JDBC connection type that PHAkT can utilize. In the Readme.txt within the original PHAkT archive it states that JDBC connections can be used, but a specific JDBC driver needs to be installed.

Why do my extensions disappear when I customize the code?

I'm sure that it's happed to everyone, an extension does Almost what you need it to.  So you, being the crazy code warrior that you are, breaks open the code view, and adds that extra if statement to the code... so you test it, and it works.  You are the king, until you have to edit a property of the server behavior, boom, it's gone from the list...

what ever shall you do!!!

Upload Problems - Permissons could hold the key

When uploading a file to your webserver most people are already aware that the folder where the file resides must have the correct permissions to accept the uploaded file.

In most cases this will be 755 or 777 (try 755 first, always leave 777 as a last resort), however, what do you do if the permissions are correct and the upload still fails ?

Determine Width and Height of uploaded image

This code was found at www.4guysfromrolla.com and is very cool.

It will most often determine whether or not a file is an image, though in rare instances it can give a false positive.  The script will then return the height, width and colour depth.

Note at the bottom is a test area to determine whether it is working.  You can change the folder so it finds some images on your system.  I have it commented out right now.

This hooks in with Pure ASP Upload V1.5 and V2.0 quite nicely.  I have used it as an include file with success.
