How to display the thumbnail please help!

**barbara1712** · Jun 15, 2007, 06:01

Hello All,

I need your help for thumbnail.I have an image gallery containing say 200 images.
All images are having different dimensions.ex image1 is 800 by 600
and image2 is 2010 by 2000.
Now I want a page which displays the thumbanail of all the images with equal size
say 125 by 125.

Please help me how do I create thumbanail of equal size for all the images which are having different dimension.

Your help will be highly appreciated.

Thanks in advance.

You can either modify the images by height or width. Otherwise you don't preserve the aspect ratio, which results in a sheered image.

You could do a batch resize. using http://www.irfanview.com/

How are the image uploaded originally? you could create a resized version when you upload the version.

I have a photography site where I created thumbnails. I used GD to process the images and resize. Works well!

Code:

function h_thumb_sizer($userfile, $width, $height){
	global $thumb_output;
	$white_border_px = '1';
	$black_border_px = '2';
	$thumb_width = '170';
	$thumb_height = '113';
	$real_path_userfile = '/path/to/originals/'. $userfile;
	$path_thumb = '/path/to/originals/thumbnails/'. $userfile;
	$dest = imagecreatetruecolor($thumb_width, $thumb_height);
	$black_color = imagecolorallocate($dest, 0, 0, 0);
	$white_color = imagecolorallocate($dest, 255, 255, 255);
	$src = imagecreatefromjpeg($real_path_userfile); 
	$final = imagecopyresampled($dest, $src, 0, 0, 0, 0, $thumb_width,    $thumb_height, $width, $height);
        // BLACK & WHITE 1PX BORDER
	imageline($dest, 1, 0, 1,111, $black_color); // LEFT SIDE
	imageline($dest, 0, 1,168,1, $black_color); // TOP SIDE
	imageline($dest, 168, 0,168,111, $black_color); // RIGHT SIDE
	imageline($dest, 0, 111, 168, 111, $black_color);	// BOTTOM SIDE
	imageline($dest, 0, 0, 0,170, $white_color); // LEFT SIDE
	imageline($dest, 0, 0,170, 0, $white_color); // TOP SIDE
	imageline($dest, 169, 0,169,112, $white_color); // RIGHT SIDE

I have tried your function but I am getting only the some portion of the image.
i.e. image is not getting resize.
Am I doing wrong?

PHP Code:


function h_thumb_sizer($userfile, $width, $height){

    global $thumb_output;

    $white_border_px = '1';

    $black_border_px = '2';

    $thumb_width = '170';

    $thumb_height = '113';

    $real_path_userfile = 'original/'. $userfile;

    $path_thumb = 'thumb/'. $userfile;

    $dest = imagecreatetruecolor($thumb_width, $thumb_height);

    $black_color = imagecolorallocate($dest, 0, 0, 0);

    $white_color = imagecolorallocate($dest, 255, 255, 255);

    $src = imagecreatefromjpeg($real_path_userfile); 

    $final = imagecopyresampled($dest, $src, 0, 0, 0, 0, $thumb_width,    $thumb_height, $width, $height);

        // BLACK & WHITE 1PX BORDER

    imageline($dest, 1, 0, 1,111, $black_color); // LEFT SIDE

    imageline($dest, 0, 1,168,1, $black_color); // TOP SIDE

    imageline($dest, 168, 0,168,111, $black_color); // RIGHT SIDE

    imageline($dest, 0, 111, 168, 111, $black_color);    // BOTTOM SIDE

    imageline($dest, 0, 0, 0,170, $white_color); // LEFT SIDE

    imageline($dest, 0, 0,170, 0, $white_color); // TOP SIDE

    imageline($dest, 169, 0,169,112, $white_color); // RIGHT SIDE

    imageline($dest, 0, 112, 169, 112, $white_color);    // BOTTOM SIDE

    $thumb_output = imagejpeg($dest, $path_thumb, 100);

    return $thumb_output;

}



if(h_thumb_sizer("myImage.jpg",600,600))

{

?>

<html>

    <body>        

<img src="thumb/myImage.jpg" />

</body>

</html>
