This script presents a file open dialog, select one type of file (by extension) and the script loads all the images with that extension from the target folder as layers to a single new document.
This script utilize the Place command of Photoshop, it is very fast. Note however that when layering large amount of data (e.g. 256 layers of 1MB images is rather large for the typical office computer) there will be a delay after the script has completed, during this delay time Photoshop is desperately trying to figure out what it was what actually just happened and does not respond to anything, the length of this delay is about half of the run time of the script. Just wait patiently, on my computer the script loads 256 layers of 1MB images in about 90 seconds and then after 45 second delay Photoshop is again responding.
