Is it just me, or do images get placed into the breads that have nothing other than the image itself. No headers on the file name (something seemingly random in the name), nothing in the body post linking back to another post or any explanation why the photo.
If thinking maps and building the map. A map would have layers and eventually get to a point of needing a keystone to hold it all together connecting one side to the other.
So how does one inspect an image for layering to see what may be contained in it, underneath, etc.?
