Image Resize

[SieRobin]

I did view source, the IMG tag looks like this for my picture.

<img src='image.php?img=userimages/me.jpg' border='0'>

Other then that, I'm not sure what you mean, sorry :\

Ok, you want to put debug statements into the image.php file. But those statements can't write to the screen. They should write to a file.

What type of platform are you using? Windows or Unix (linux)

Here's how I would do it:
[code]<?php
function write_debug($fp,date('Y-m-d G:i:s') . $str) {
   f write($fp,$str . "\n");
}

session_start();
$dbg = (isset($_GET['dbg']))?true:false;
if ($dbg) {
    $fp = f open('image_debug.txt','a');
    write_debug($fp,' --  Entering image.php');
    write_debug($fp,' -- $_GET --');
    write_debug($fp,print_r($_GET,true));
    f close($fp);
}
if (isset($_GET['img'])) {
// $img_name = "userimages/$pstats3[uimage]"; // <--- this statement is wrong -- my mistake sorry
   $img_name = $_GET['img'];
$max_width    = 150;
$max_height   = 150;
$size=getimagesize($img_name);
$width_ratio=($size[0] / $max_width);
$height_ratio =($size[1] / $max_height);

if($width_ratio>=$height_ratio)
{
   $ratio=$width_ratio;
}
else
{
   $ratio=$height_ratio;
}
$new_width=($size[0] / $ratio);
$new_height=($size[1] / $ratio);
header("Content-Type: image/jpeg");
$src_img = imagecreatefromjpeg($img_name);
$thumb = imagecreatetruecolor($new_width,$new_height);
imagecopyresampled($thumb, $src_img, 0,0,0,0,($new_width-1),($new_height-1),$size[0],$size[1]);
imagejpeg($thumb);
imagedestroy($src_img);
imagedestroy($thumb);
exit();
}
?>[/code]

While I was added the debug code to your image.php I noticed what the problem is. See the comment above with the "<---" in it.

The next line is the corrected line.

If changing that line works, you don't have to put in the debugging lines.

In the debug area I had to write the file functions with a space in them.

ahha, it works :] Thank ya!

Just one more question, I'm pretty sure it's easy to answer.. well since the only thing the code seems to accept is JPEG is there a way to allow GIF and PNG?

[SieRobin]

How exactly can I make it also accept GIF files and not just JPEG? Because, right now it will only display if it's in JPEG format.

forgive me if i am wrong but i would think you would just need to modify this line

header("Content-Type: image/jpeg");

i dont know the syntax but i would make it something like this

header("Content-Type: image/jpeg/JPEG/GIF/gif/PNG/png");

does that work??

[SieRobin]

My server is down right now but, I don't think that'd work since, it's asking it to createfromjpeg.. now if I were to put createfromgif it would allow all GIF extensions, but I can try it, never hurt to try.
