Luminosity Photo Mosaic v1.0 by Mehmet Sensoy

Finally this is available and ready in the FF Library although the description given I think is not enough to understand how this filter works and the presets can be misleading

Please, to see really how this filter was created and what is the real way to use it see the original thread here

Tile Gradient with custom row and column cut amount from left to right

There are included two 10x10 image grid images for you to use with this filter

In the Filter description appears Please also read the comments section

Do you mean to read a comment that you will put here in this page?

------------------------------------------------
THERE ARE TWO WAYS TO USE THIS FILTER AS I SEE IT
------------------------------------------------

OPTION 1 - USING IT WITH ONE SINGLE SOURCE IMAGE

This is as it is already done when you download the filter, BUT this is not at all the way it should be as it was NOT designed to work this way, and you need to see the option 2 below to see how it really works and how it was designed to work

This way also gives interesting and Cool results too

Step 1 - First You load a image with File --> Open Image...

This image will be used as source for the contour and shape of the mosaics that are going to be distributed

Also this image will give the final resolution result will have

Step 2 - Load any image in the Tile Map option that may want to be broken into tiny bits that will fill all the small mosaics

USING A 10x10 GRID OF IMAGES MADE IN ONE SQUARE IMAGE

This is how it is really works correctly. It was not possible to include this way by default because Filter Forge does not allow to submit filters with external images

Step 1 - First You load a image with File --> Open Image...

This image will be used as source for the contour and shape of the mosaics that are going to be distributed

Also this image will give the final resolution result will have

Step 2 - Load a image that contains a 10x10 Grid of square images in the Tile Map option

And so the filter will cut them out and distribute them all around the source image loaded in step 1

HOW TO MAKE A 10x10 GRID IMAGE WITH YOUR OWN IMAGES

Well, I have not yet the explanation and way to do it, as it depends on what software you have available.
