Thanks to the multi-talented [url=]whoo[/url] helping me in [url=]this thread[/url], I've started playing with image creation in PHP again...

Some samples:

More to follow shortly, soon as I get some more ideas...

"Right-Click, and Save your image! It will be auto-deleted in 5 minutes!" ?

Are you saving the generated image to a file?

And nice idea btw.

balupton, yep. it's easier to manipulate the image that way. It's saved as a temp file for 5 minutes, then deleted.

How i've done it in the past would just be:
And it would change the content header to whatever image it is.

Or by changing the .htaccess file, you can do stuff like

Which would actually use image.php?bg=1&text=hello&outputas=png

Don't really see why you would want to save the file...

Well, in my case, I was programming it at 4am, hadn't slept at all that night, and it was easier. :) Don't question my madness.

Haha, ok ;)

I'm curious how you do the auto-delete though.... May come in handy for the future.

Not a problem...

I have the following code stuck at the end of index.php (the images are saved in a subdirectory called display)...

$dpath ="display";
if (is_dir("$dpath") )
while (false!==($dfile = readdir($dhandle))) {
if ($dfile != "." && $dfile != ".." && $dfile != "index.php") { 
$diff = (time() - filemtime("$dpath/".$dfile)); if ($diff > 60*15) unlink("$dpath/".$dfile);

The 60*15 part is where you set your duration (in this case, 15 minutes)

Wouldn't that cause quite a performance hit on the server...

Not really. And I even submitted it to Fark. :)
