This is equivalent to two downloads, depending on the speed of your server, it will certainly be slow.

Since you want to get the image size, size, and format, it is better not to use php. you can use js to get the image. This way, the computation is all obtained by the client.

Using this function to obtain remote image information is slow.
You can try to useget_file_contentGet, save to local, and thenimagegetsizeTo see if it can be faster.
