How Can I Create Thumbnails

AMBATES

Hello,

I have tried and tried, and getting nowhere, I have written code to create thumbnails, however, I can only display the thumbnail by its self, If I add text above it, or anything, It displays the image as text.

Example

How do I create thumbnails within HTML, all I want to do is make thumbnails from the images within a directory.

Please help, I am stuffed!

im not familiar with using this, so i dont know if it works. bu i can try 🙂

$image = '/images/logo.gif';
$size = getimagesize ($image);
$size = explode (' ', $size[3]);
$size[0] = explode ('=', $size[0]);
$size[1] = explode ('=', $size[1]);

$height = $size[0][1] / 10;
$width = $size[1][1] / 10;

echo '<img src="/images/logo.gif" height="' . $height . '" width="' . $width . "' alt="logo" border="0" />';

that would print the image 10% of the original size, so just play around with the '/ 10' a bit

is that what you were lookin for?

Thats what I did the first time, howver, if you get pics of 1mg in size, and your thumbnailing about 10 pictures it causes problems, So i need to actually recreate the image.

cockney

function imagezoom(&$im,$x1,$y1,$x2,$y2,$ratio)
{
$new = imagecreate(($x2-$x1),($y2-$y1));
$zoomed = imagecreate((int)($ratio($x2-$x1)),(int)($ratio($y2-$y1)));
$copy = imagecopy($new,$im,0,0,$x1,$y1,($x2-$x1),($y2-$y1));
imagedestroy($im);
$im = imagecreate((int)($ratio($x2-$x1)),(int)($ratio($y2-$y1)));
$resize = imagecopyresized($im,$new,0,0,0,0,(int)($ratio($x2-$x1)),(int)($ratio($y2-$y1)),(int)($x2-$x1),(int)($y2-$y1));
imagedestroy($new);
}

look at the manual to suss out the individual functions.

example use ;

             $ratio = .25;
             $img = imagecreatefromjpeg($userfile);
                  $imageInfo = getimagesize($userfile);
                  $width = $imageInfo[0];
                  $height = $imageInfo[1];
             imagezoom($img,0,0,$width,$height,$ratio);
             ImageJPEG($img,$targetdir."/".$thumbnailname);
             imagedestroy($img);
