This PHP class uploads files and manipulates images very easily. It is in fact as much as an image processing class than it is an upload class. Compatible with PHP 4, 5, 7 and 8. Supports processing of local files, uploaded files, files sent through XMLHttpRequest.
This adds an example for the multiple attribute of the file picker. See https://caniuse.com/#feat=input-file-multiple
Changed also the CSS from float layout of the examples to flex layout.
