How to Use Photoshop for automatic Photo Collages of +1000 photos

In FIlter Forge there is already available the awesome and well done automatic Auto Collage by ThreeDee but the problem with this is that is limited to 16 photos and you have to load them all one by one manually

If FF could be able to have a way to load images from a folder would be really incredibly awesome, but that I think will not happen

Well, If you have Photoshop CC, I have found a way to be able to make automatic photo collages with hundreds or thousands of photos that are positioned correctly without overlapping and perfectly distributed photos of any size and ratio and load automatically your selected photos

The only bad thing is that you will not be able to add and customize the edges frames of the photos as it happens in ThreeDee filter

Here is tutorial that shows you step by step how to do it easily
