Image JPG/GIF

[jaymc]

I have an upload script that allows people to upload images, adds a bit of text on the image then displays it

This works great, but, here is the problem

It only works if the file was saved as a JPG!

If the image the upload is a gif, then the image does not display. My script needs to support atleast jpeg, gif bmp & png

Obviously imagejpeg() does not support anything other than true jpg files

Any way around it / alternitives?

Are you using imagecreatefromjpeg()? You need to use imagecreatefromgif() if you want to load a GIF image.

well the problem is, the gif files are saved as .jpg

So they are true gif files but named file.jpg, so I cant determine if they are gif or not as I cant go by the file extension

Perhaps if you posted some code we wouldn't have to guess what's wrong.

[code]<?
// File and new size
$userpic = $_GET['user'];
$filename = "pics/".$userpic.".jpg";


// Content type
header('Content-type: image/jpeg');

  // Date in the past, so that the image is not cached by the browser
Header("Expires: Mon, 26 Jul 1997 05:00:00 GMT");

// Get new sizes
list($width, $height) = getimagesize($filename);
$newwidth = 76;
$newheight = 62;

// Load
$thumb = imagecreatetruecolor($newwidth, $newheight);
$source = imagecreatefromjpeg($filename);

// Resize
imagecopyresampled($thumb, $source, 0, 0, 0, 0, $newwidth, $newheight, $width, $height);


// Output
imagejpeg($thumb, null, 100);
?> [/code]

getimagesize() will also tell you the type of the file

list($width, $height, $type) = getimagesize($filename);

Use the type info to adjust your code accordingly

Great, Ive got it working using the following approach
[code]if ($type[2] == 1) {$source = imagecreatefromgif($filename);}
else if ($type[2] == 2) {$source = imagecreatefromjpeg($filename);}
else if ($type[2] == 3) {$source = imagecreatefrompng($filename);}
else if ($type[2] == 4) {$source = imagecreatefromjpeg($filename);}
else if ($type[2] == 6) {$source = imagecreatefrombmp($filename);}[/code]

However, their is no [b]imagecreatefrombmp[/b]

How do I handle bmp images?

Not supported by GD. But if you want to process them
