Image Problems

[cmgmyr]

ok I have a little photo gallery on a site. I made up a little bit of code that resizes the image if it is too big.

The script works fine when it's on my local computer, but when I upload it the script takes the image size of the image after the one it's supposed to, but outputs the image it is supposed to.

If I have image1 and image2, When I try and get the size of image1 it takes the size of image2, but still outputs image1...I don't get it...here is my code, please help if you can!

[code]    if (!isset($userid) or trim($userid)=='') {
      $gal = 1; }
    if (!isset($pic) or trim($pic)=='') {
      $pic = 1; }
    $dir= "custphotos/gallery".$userid;
    @$d = dir($dir);
              
    if ($d) {
      while($entry=$d->read()) {  
        $entry = preg_replace("/ /","%20",$entry);
        $pos = strpos (strtolower($entry), ".jpg");
        if (!($pos === false)) {  
          $arr_pic[] = $dir."/".$entry; } }
      $d->close(); }
    
    $CONST_WIDTH = 250;
    //Find image h and w
    $size = getimagesize($arr_pic[$pic-1]);
    
    $w = $size[0];
    $h = $size[1];
    
    if($w > $CONST_WIDTH){
        //Find %
        $percent = $w / $CONST_WIDTH;
        $w = $w / $percent;
        $h = $h / $percent;
    }
    
    @sort ($arr_pic);    
    $total  = sizeof($arr_pic);
    echo "<div align=\"center\"><img width=\"$w\" height=\"$h\" src=".$arr_pic[$pic-1]."><br>";[/code]

[redarrow]

a guess


$w = $size[0];
$h = $size[1];

This
[code]
$w = $size[0];
$h = $size[0];
[/code]

or

[code]
$w = $size[1];
$h = $size[1];
[/code]

good luck only learning my self please always back you files up.

Nope, still didn't work. Any other ideas out there???

Could be that the array sort is screwing up the array indexes.

[cmgmyr]

So what do I have to do to fix it?

What are the PHP versions on both your local machine and the host?

looking at your code and at the post by [b]Barand[/b], I think he's hit the nail on the head. Have you tried what he suggested? Lose the @sort line (for the purpose of testing) and see what happens.

Ok...that fixed the size problem...but caused another.

The customers are allowed 5 photos. I originally had it set up to where they can re-name the photos to change the order of them on their profile, but now it's not working like that. The way that it is set up now it shows the second picture [$pic-1] when I try [$pic-2] none of the images show up.

Is there a way to get around this one?

Thanks

try changing the second part of your code

[code]    $CONST_WIDTH = 250;
    @sort ($arr_pic);

    foreach ($arr_pic as $picfile) {
        //Find image h and w
        $size = getimagesize($picfile);

        $w = $size[0];
        $h = $size[1];

        if($w > $CONST_WIDTH){
            //Find %
            $percent = $w / $CONST_WIDTH;
            $w = $w / $percent;
            $h = $h / $percent;
        }
        echo "<div align=\"center\"><img width=\"$w\" height=\"$h\" src=\"$picfile\"><br>";
    }
[/code]

[cmgmyr]

FIXED!

I moved the sort more to the top:[code]@sort ($arr_pic);
$CONST_WIDTH = 250;[/code]

Thanks for all of your help!
