Problem with with Image Resizing Code

[svgmx5]

I've been working on this site that allows users to upload images to the server...

 

the code i have right now basically uploads the file to the server and then resizes it and makes a new copy of it...

 

Upuntil now it was working flawlessly, however now i'm getting this error:

Warning: imagecreatefromjpeg() [function.imagecreatefromjpeg]: gd-jpeg: JPEG library reports unrecoverable error: in /home/content/t/h/e/thereferralpro/html/beta/region.php on line 144

Warning: imagecreatefromjpeg() [function.imagecreatefromjpeg]: 'images/projects/porncheck_star.png' is not a valid JPEG file in /home/content/t/h/e/thereferralpro/html/beta/region.php on line 144

Warning: imagecopyresampled(): supplied argument is not a valid Image resource in /home/content/t/h/e/thereferralpro/html/beta/region.php on line 162

Warning: imagedestroy(): supplied argument is not a valid Image resource in /home/content/t/h/e/thereferralpro/html/beta/region.php on line 165

 

In order for you guys to understand the error here's the code i'm using

//move file to the folder before resizeing
									move_uploaded_file($_FILES['image']['tmp_name'], $target);

									//resize the image and add to server
									$source_pic = $target;
									$final_pic = $dir.$final_img_name;
									$max_width = 800;
									$max_height = 600;

									$src = imagecreatefromjpeg($source_pic);
									list($width,$height)=getimagesize($source_pic);

									$x_ratio = $max_width / $width;
									$y_ratio = $max_height / $height;

									if( ($width <= $max_width) && ($height <= $max_height) ){
										$tn_width = $width;
										$tn_height = $height;
									}elseif (($x_ratio * $height) < $max_height){
										$tn_height = ceil($x_ratio * $height);
										$tn_width = $max_width;
									}else{
										$tn_width = ceil($y_ratio * $width);
										$tn_height = $max_height;
									}

									$tmp=imagecreatetruecolor($tn_width,$tn_height);
									imagecopyresampled($tmp,$src,0,0,0,0,$tn_width, $tn_height,$width,$height);

									imagejpeg($tmp,$final_pic,80);
									imagedestroy($src);
									imagedestroy($tmp);

									list($width, $height, $type, $attr) = getimagesize($final_pic);

 

Keep in mind that this code was working perfectly and now for some reason its not working anymore, and no i have not touch it at all nor i have done nay edits to this code

 

Hope someone can help me out because i have no idea what this could be.

 

Thanks

It looks like is because you are uploading a png file and not a jpg file so it is causing the error

[svgmx5]

its happening with any images...

 

and i was able to upload all types of images before...this just started happening today

 

iv'e checked my php info and i do have the latest gd library: bundled (2.0.34 compatible)

Okay,

 

so i just migrated the whole site to a different server and its working properly...could this be a server issue??

It's probably more that the new server has error reporting disabled.

 

It's more likely in your code itself because you can be checking what the mime should be...then of those results then do a case for any imagecreatefrom, then also a case for the output of that exact mime type as well.

 

Look here , you are trying to create from a jpeg image when actually it's a png image.

I believe godaddy has display errors on globally. That's where you were getting the errors, yes?

Actually i encountered a similar problem awhile back, the problem is more on the image app they are using to save the image.

I found some image apps did not work correctly with the gd functions while others did.

 

An option u may have open, is to use imagemagick or netpbm to do the conversions for u, if you have these packages available to your server as well as system function in your php configuration.

 

the other option is switch image app and testing which apps work with gd correctly. from there its just a matter of resaving the image with the ones u found to work.

You need to check them like this and then use the proper imagecreatefrom.

 

$ext = substr($image_source, strripos($image_source, '.'),strlen($image_source));

    if($ext=='.jpg' || $ext=='.jpeg'){
        $image = imagecreatefromjpeg($image_source);
        }
    if($ext=='.gif'){
        $image = imagecreatefromgif($image_source);
        }
    if($ext=='.png'){
        $image = imagecreatefrompng($image_source);
        }
if ($ext != ".jpg" || $ext != ".jpeg" ||  $ext != ".gif" || $ext != ".png") {
die("<h2>$ext not allowed</h2><br />
<a href=\"javascript: history.go(-1)\">Click here to try again</a>");
}

Actually someone was nice enough to already write a tutorial at php freaks on image resizing and posted the code.
