PHP thumb uses the GD library to create thumbnails from images (jpeg, gif, png etc) on run time.
You can configure the output size and source will be entire image or a portion of original image.
PHP uses imagejpeg function which output image to browser or file.
bool imagejpeg ( resource $image [, string $filename [, int $quality ]] )
Returns TRUE on success and FALSE on failure.
Below are the two functions for thumbnail creation and merging two images.
<?php function createThumbs( $pathToImages, $pathToThumbs, $thumbHeight, $fname ) { $info = pathinfo($pathToImages . $fname); if ( strtolower($info['extension']) == 'jpg' ) $img = imagecreatefromjpeg( "{$pathToImages}" ); if ( strtolower($info['extension']) == 'gif' ) $img = imagecreatefromgif( "{$pathToImages}" ); if ( strtolower($info['extension']) == 'png' ) $img = imagecreatefrompng( "{$pathToImages}" ); $width = imagesx( $img ); $height = imagesy( $img ); $new_height = $thumbHeight; $new_width = floor( $width * ( $new_height / $height ) ); $tmp_img = imagecreatetruecolor( $new_width, $new_height ); imagecopyresized( $tmp_img, $img, 0, 0, 0, 0, $new_width, $new_height, $width, $height ); if ( strtolower($info['extension']) == 'jpg' ) imagejpeg( $tmp_img, "{$pathToThumbs}{$fname}" ); if ( strtolower($info['extension']) == 'gif' ) imagegif( $tmp_img, "{$pathToThumbs}{$fname}" ); if ( strtolower($info['extension']) == 'png' ) imagepng( $tmp_img, "{$pathToThumbs}{$fname}" ); } ?>

Hi Riyaz,
You need to call the function "imagemerge" with all parameters.
Create a folder "images" in the same path and put an image called "white.jpg" just like "images/white.jpg".
Then call the function:
imagemerge('sample-1.jpg','sample-2.jpg',400,400,'final.jpg');
You need to adjust the height and width as per white image.
Thanks.
Sir I was try this with all parameters but its not work for me can you create this functions than send me a zip file
Thanks you....
You need to put all there images in your file path.
1) first image. 2) second image and 3) a simple white.jpg in images folder.
Then call the function as below:
imagemerge(‘sample-1.jpg’,’sample-2.jpg’,400,400,’final.jpg’);
Thanks.
