Updatable sig pic

I would like to have the facility to create my own updatable sig pic with all the relevant images, etc on my own webspace.

I have had ones created using other peoples facilities, but it stores the info locally on their server & if that goes down for any reason all I get is the lovely red cross box, which really bugs me.

Any ideas/help please? :confused:

Looks like yours is hosted by Barry, he was having to move stuff around yesterday I think it was. Maybe thats why it’s not working at the minute.

Well that answers that at least. Thanks Ren.

New sig maker will be up and running soon, just need to finish the database off :slight_smile:

Cheers Barry. I like playing with software to see what it will do & this seemed like an ideal bit to play with. I’ve been having a look at the PHP website (www.php.net) for tips, but it looks like I’m on a learning curve.

HTML was easy, this is a little more of a challenge though. Any tips or pointers you can suggest would be gratefully received. :thumbsup:

easyest way is to use this, need GD installed on your server to use it.
