Can somone modify this so it will resize ALL the images in a specific folder instead of just one? I haven't actually tested this script to see if it works with just one image, but assuming it does work that way, all I need done is make it work with a folder of images not just one image like it shows: $image = "../path/fileName.gif";

PHP Code:

<?php
$image = "../path/fileName.gif";
if (file_exists($image))
{
  list($width) = getimagesize($image);
  // set the maximum width of the image here
  $maxWidth = 100;
  if ($width > $maxWidth)
  {
    echo "<p><img alt=\"Image\" width=\"$maxWidth\" src=\"$image\" />";
  }
  else
  {
    echo "<p><img alt=\"Image\" src=\"$image\" /></p>\n";
  }
}
else
{
  echo "<p>Image does not exist</p>";
}
?>

Thank you

Are the names from the images random? Or is it just like:
1.jpg 2.jpg 3.jpg

PHP Code:

$dir = '../path/';
$handle = opendir($dir);
while($image = readdir($handle))
{
     //your existing code here
} 


I tried as you said Null, and all I see is a blank white screen. I checked the code for syntax errors, but don't see any. :S

PHP Code:

<?php

$dir = '/images/';
$handle = opendir($dir);
while($image = readdir($handle)) 

{
  list($width) = getimagesize($image);
  // set the maximum width of the image here
  $maxWidth = 100;
  if ($width > $maxWidth)

  {
    echo "<p><img alt=\"Image\" width=\"$maxWidth\" src=\"$dir\" />";
  }
  else
  {
    echo "<p><img alt=\"Image\" src=\"$dir\" /></p>\n";
  }
}
else
{
  echo "<p>Image does not exist</p>";
}
?>

readdir returns the file name, not the full path. I think this should do it:

PHP Code:

<?php

$dir = '/images/';
$handle = opendir($dir);
while(false !== ($image = readdir($handle))) 

{
  list($width) = getimagesize($dir . $image);
  // set the maximum width of the image here
  $maxWidth = 100;
  if ($width > $maxWidth)

  {
    echo "<p><img alt=\"Image\" width=\"$maxWidth\" src=\"$dir\" />";
  }
  else
  {
    echo "<p><img alt=\"Image\" src=\"$dir\" /></p>\n";
  }
}
else
{
  echo "<p>Image does not exist</p>";
}
?>

Still getting a blank screen, not even echoing out an error. I think it's something with the readdir part, but not too sure, that's why I am asking...

Try echoing $image to see if it is being set properly. Also, your last else condition (following the while loop) is not valid.

Try this:

PHP Code:

<?php
$dir = "images"; //dir of your images
$exten = "jpg"; //extension -> jpg / gif / png
if ($handle = @opendir($dir)) 
{
    while (false !== ($file = @readdir($handle))) { 
        $bestand = $dir ."/". $file;
        $ext = pathinfo($bestand);
        if($ext['extension'] == $exten)
        {
            echo "<p><img src='$bestand'></p>" ;
        }
    }
    @closedir($handle); 
}
?>

If this works, you can set a max-width etc

This works, but need to be able to set set max with and allow all 3 file types at the same time, not choose because the images are already in the directory as gif, jpg, png.

Thank you for you help Bertjeuh

Tried that, not working either, should have thought of that right away, but it didn't work anyway.

I would love to get one of these scripts working, any of you guys having any luck with them? Like I said, the one from nullpointer did not work at all (output was white screen) and the one from Bertjeuh echo's the image but doesn't resize and I tried putting the $maxwidth variable and couldn't get any output but a white screen.

PHP Code:

<?php
$dir = "images"; //dir of your images
$exten1 = "jpg"; //extension -> jpg / gif / png
$exten2 = "png"; //extension
$exten3 = "gif"; //extension
$maxwidth = '100'; //maximum widht
if ($handle = @opendir($dir)) 
{
    while (false !== ($file = @readdir($handle))) { 
        $bestand = $dir ."/". $file;
        $ext = pathinfo($bestand);
        if($ext['extension'] == $exten1 || $ext['extension'] == $exten2 || $ext['extension'] == $exten3)
        {
            $width = getimagesize($bestand);
            if($width[0]<$maxwidth)
            {
                echo "<p><img src='$bestand'></p>" ;
            }
            else
            {
                echo "<p><img src='$bestand' width='$maxwidth'></p>";
            }
        }
    }
    @closedir($handle); 
}
?>

Wow, thanks Bertjeuh, that works! Happy Thanks Giving!

This isn't really that important, but is there another way to add alt text from a mysql table than this:

title=\"$row[element_1]\"

that way doesn't show anything...I am using firefox and have also tried alt in replace of title and that didn't work either, knowing already that alt is for ie browsers only.

That should work. Right click on the website and check the source code to see if there's actually anything there, perhaps it has no value, as in title="".

Thanks mr Bertjeuh this coding is working fine.

                    }
            }
    }
closedir($diropen);
}
?>

I modified above code its also working fine.
