is it possible to add png files and then use it as sprites?

When you add a .png file, you'll get its base64 code as the file_source parameter. You should be able to convert this base64 to a sprite,

Here's what I found on Yoyogames Forums.

var buff=buffer_base64_decode(base64string); //Use async_load[? "file_source"] for this argument
