Hello, I was just wondering how I would go about making an image that updated with information ?

PHP: imagestring - Manual

[xEX3CUT1ONx]

Okay, that is kinda what i was looking for however, I was wanting a complex image, so my plan was to make it in photoshop then using css I would have styled it, and made areas for the text to go, is there anyway I can still do that ?

To show what I mean, here is a xbox live gamercard from another website: http://card.mygamercard.net/h2o/xEX3CUT1ONx.png

I want to make something similar to that, I already have the xbox live information, I'm just unsure on how to get it into image form like that one is, would the imagestring method work someway ?

You can still use the function Nico suggested.

You would load your base photoshop PNG using gd functions. f you are using a PNG and have transparency make sure you account for that. You are not going to be able to use CSS styles on the text in the image.

You want to make your string to appear on the background base image. If you are using a special font make sure you load it first. Call imagestring on your image resource object specifying the coordinates where you want your text to appear. Then save the resource to a new file.

Okay, I've been messing around with the imagestring function, and I may be overlooking things, but it looks like I can only have one string of text per image, as in the sample I posted there is a lot of different strings used, along with images.

You can call imagestring() multiple times if you need more text. You just have to change the positions accordingly.

As for the images, take a look at: PHP: imagecopymerge - Manual

Okay thanks everyone, I'll have a go
