How to Create Image Thumbnails
How to Create Image Thumbnails Image thumbnails are basically a smaller size copy of a larger image. They can be created using PHP GD Library functions alongside a file system function that we already learned about. The getimagesize() file function will return the dimensions of the image specified. It can be used together with the list() function to minimize code and effort. The imagecopyresampled() function can be used to stick a smaller version of an existing image into a new (smaller) image, thus creating a thumbnail. The syntax is: imagecopyresampled(resource $dst_image, resource $src_image, int $dst_x, int $dst_y, int $src_x, int $src_y, int $dst_w, int $dst_h, int $src_w, int $src_h) dst_image = Destination Image src_image = Source Image dst_x = X Coordinate of Destination Image dst_y = Y Coordinate of Destination Image src_x = X Coordinate of Source Image src_y = Y Coordinate of Source Image dst_w = Destination Width dst_h = Destination Height src_w =
