$source_image = imagecreatefromjpeg('path/to/image.jpg');
$source_image = imagecreatefromgif('path/to/image.gif');
$source_image = imagecreatefrompng('path/to/image.png');After creating the image from the file, you can now insert it into another image using the imagecopy() function. Here's an example: ``` $destination_image = imagecreatetruecolor($width, $height); //create a new image with the desired width and height imagecopy($destination_image, $source_image, $dest_x, $dest_y, $src_x, $src_y, $src_width, $src_height); ``` The above code snippet demonstrates how to insert the source image into a destination image at the specified position. The `$dest_x` and `$dest_y` variables represent the position in the destination image where you want to insert the source image. The `$src_x` and `$src_y` variables represent the coordinates in the source image where you want to start copying from, while the `$src_width` and `$src_height` variables represent the width and height of the portion of the source image you want to copy. In conclusion, the GD Library package provides various PHP functions that allow you to insert images into other images. The imagecreatefromxxx() functions are used to load the source image, while the imagecopy() function is used to insert it into the destination image.
