Creating thumbnails is actually fairly simple in PHP, for a simple scale/stretch you can do the following:
$image_path = '/path/to/image'; $thumbnail_path = '/path/to/thumbnail'; $thumbnail_width = 100; $thumbnail_height = 100; $thumbnail_quality = 60; $image = imagecreatefromjpeg($image_path); $imagex = imagesx($image); $imagey = imagesy($image); $thumbnail_image = imagecreatetruecolor($thumbnail_width, $thumbnail_height); imagecopyresampled($thumbnail_image, $image, 0, 0, 0, 0, $thumbnail_width, $thumbnail_height, $imagex, $imagey); imagejpeg($thumbnail_image, $thumbnail_path, $thumbnail_quality)
Bearing in mind that this is setup for jpegs only. For other file formats PHP has corresponding functions – imagecreatefrompng, imagepng, imagecreatefromgif, imagegif etc
Also if you don’t provide a thumbnail path to the imagejpeg function then the image will be rendered directly, allowing you to have dynamically generated thumbnails.
