[SOLVED] imagecreatefrom[type]() detector help

[Kairu]

Alright, I'm having a bit of a problem. When I put my code together I did not anticipate php files outputting different file types.

I was using this for a short time to separate file types before I tried to use a php file...

[code]if (strpos($sig, '.jpg') !== FALSE) {
$image = imagecreatefromjpeg($sig);
}
elseif (strpos($sig, '.png') !== FALSE) {
$image = imagecreatefrompng($sig);
}
elseif (strpos($sig, '.gif') !== FALSE) {
$image = imagecreatefromgif($sig);
}
elseif (strpos($sig, '.bmp') !== FALSE) {
$image = imagecreatefromwbmp($sig);
}
else {
$image = imagecreatefromgif($sig);
}[/code]

Is there a better way to do this? Or perhaps one will work for all file types? 

I guess I could request the files be the same, but that would bee too much trouble if they do not have access to the file.....

Any help would be appreciated!

A filename ending in ".jpg" doesn't guarantee the file is actually a JPEG.
Take a look at imagecreatefromstring()

Aaaahhhhhh....... I couldent get it to work at first, but then found an example.... You need to place file_get_contents() into it to make it work.... correct?

Yes
