The trial version limitation

[M]

The maximum size of 15x15 means :
1. the export only allowed under 15 grid by 15 tiles in the editor? (no matter how big the image size is?)
2. Or the means I need to set the tile size = 15 (in the first page when I opened the editor)
3. Or the "skin" image size need to be under 15pixels by 15 pixels?

15x15 is referred to the map (grid) size. So you can export maps which are made of 15 tiles x 15 tiles max.
