Generating LARGE Images

[i8bit]

Backround Information:
Let's say you are on a gmap.... Level_a1, Level_a2, Level_b1, etc etc.

If you place an NPC that generates an Image at the top left of Level_a1 and the image is larger than the level size itself, will it:

1. Even show the image at all?

2. Lagging?

3. If you re-log onto the server at Level_a2 where the image is suppose to be showing, will it show it even though the NPC drawing the image is not in that specific level?
