Column-1 bad-set's. (recycled topic)
Azoo uses large (4k x 4k) CSS-master-frame source images that are split up into the smaller 256x256 Azoo-set images.
A Column-1 Azoo set is a set that comes from the left-most column of this grid.
- The related image always fall in the grid-id range [1..17]
- In the imaginary image name, "01_12JAN31_N90123_0123-45-...", 45 is the grid-id part.
Just about all Column-1 Azoo-sets are suffering from the same kind of bad image characteristics.
