'gd' headers... help LOL

[UrbanRyan]

Right I wanna make a 'gd' header so they're so called, but I've got a bit lost when it comes to adding the border around it.

So far I've got this..

& the php code I've used is..

Just wondering what the border tag is, if anyone could help me I would appreciate it very much. Also if its possible a shadow code, but I'm not sure if it is.

I've only got a rep power of 2, but I'll still give you +rep any how.

There is no code there to make a border. However to do so the method is this:

Create the text in the colour of the border, make it bigger than you want the normal text to be (this will be the border).

Sit the normal text smack bang in the middle of it (this will be the normal text that you read, not the border)

Render it.
