Codeigniter - Watermark and Thumbnail Creation

I have been working on a photography website for quite sometime now. One of the requirements from my client is to have a watermark on the images that they upload for their clients to view. An additional requirment (on my end) is to create a thumbnail of every image that gets uploaded.

Codeigniter offers a vast array of helper files and libraries that help push along web development, among these aids is an Image Manipulation class.

In working with this class, I kept running into issues when trying to create a watermarked image and a thumbnail of the same image. Problems included not creating the thumbnail but creating the watermark, creating the watermark but not the thumbnail, creating a watermark and a thumbnail but not resizing the thumbnail, creating a watermark and a thumbnail but resizing the original image without creating a thumbnail size image, and the list goes on...

Here is how I fixed my problem

//Settings to create watermark overlay
$config = array();
$config["source_image"] = "/path/to/image";
$config["image_library"] = "gd2";
$config["wm_type"] = "overlay";
$config["wm_overlay_path"] = "/path/to/watermark/overlay";
$config["wm_vrt_alignment"] = "bottom";
$config["wm_hor_alignment"] = "center";
$config["wm_vrt_offset"] = 20;
$this->image_lib->initialize($config);
$this->image_lib->watermark();
$this->image_lib->clear();
unset($config);

//Move watermarked image into user account folder
//The below function moves the watermark image into the clients photo directory
$this->_moveimage($image, $account, FALSE);
			
$thumb_config["source_image"] = "/path/to/watermarked/image";
//You are supposed to use a brand new image name here, I usually add a prefix of copy_ or thumb_
$thumb_config["new_image"] = "/path/to/new/image";
$thumb_config["maintain_ratio"] = TRUE;
$thumb_config["width"] = 125;
$thumb_config["height"] = 125;
$this->image_lib->initialize($thumb_config);
$this->image_lib->resize();
$this->image_lib->clear();
unset($thumb_config);

And there ya go! You have a CodeIgniter script that watermarks and thumbnails an image.
