My question is :
When are the Static Map API synchronized with the current Google Maps DB?
I made a small code that gives me the following URL to a static map :
But when you ask Google Maps to show you the actual reality, it gives you another picture, which is up to date ! (coords : 50.585606, 5.563505).
Please, consider my bad level in english.
EDIT: This seems to be Issue 8910: Static map shows different satellite tiles than Google Maps. Please star that issue to keep track of interest on it, and to receive updates.
Imagery updates may not always be perfectly in sync, but at least you can subscribe to them in Google's Follow Your World tool.
