You can use the height and width attributes of the <img> tag to adjust the size of the image.

@ Motoma

here the page shows the all the images which user has uploaded, if i use the height and width to reduce the image display size, eventually the page will take much time to load...

hope i'm clear...

thkx for replying

Hi Deejam

In that case, you can as well write your own image resizing function. Not a big deal. Get the size of the image using the getimagesize function. Store the return values in a variable. Perform reduction on the width and the height returned by the getimagesize function and then return the new reduced width and heigth to the width and height parameters in the img tag.

More if you need help

Cyberking's method is valid; if you want to do more research on this method, you should look up the PHP GD functions.

Thanks cyberking and Motoma...

here is the code for creating thumbnail to the uploading picture...

echo "Creating thumbnail for $filename <br />";
// Load image and get image size
$orgimg = imagecreatefromjpeg($filename);
$width = imagesx($orgimg);
$height = imagesy($orgimg);
// Setting new width and height for thumbnail size
$newwidth = 100; //any size as you wish
$newheight = floor($height*($newwidth/$width));
// Creating new temporary image
$tmpimg = imagecreatetruecolor($newwidth, $newheight);
// Copy and resize old image into new image
imagecopyresized($tmpimg, $orgimg, 0, 0, 0, 0, $newwidth, $newheight, $width, $height );
// Save thumbnail into a file
imagejpeg($tmpimg, $path_to_thumbs_dir.$filename);


i welcome any suggestion/correction...
