You could use dingbat fonts at a large font size
as templates to make selections with Magic Wand.

Put the templates on their own layer, make the Magic Wand selection,
copy from the camo layer, paste into the chosen background layer (jungle, etc.).
Or you could cut objects out of existing pictures, and place them in new backgrounds.
Then use the same selection to copy camo and paste it into a new top layer.
Set the layer Blend mode to Multiply or another mode that will allow some transparency.
