I don't know a built-in feature that allows to do that except readying the content byte-wise and interpreting the values like explained for C++ in C++ How to get the Image size of a png file (in directory)

The image package seems to provide this functionality though. decodePng returns an image that has a width and height property.

The build-in function decodeImageFromList() can help you with that. Its callback contains an Image that includes the width and height.
