Makes large images with one to four images per page and rest empty alpha channel

[macmanmatty]

sometimes when packing large amounts of images 100000+ It makes very large 2048 x 2048 images with about zero to four images per page. The rest of the image is empty alpha channel. There are about 8000 to 200000 pages created when it does this. Not sure why it does that. Can it pack images in folders or do I have drag the all of the images manually instead of the folder? Would selecting both use fast algorithm and grid layout do this?

this only happens when force grid is selected
