As I recall there should be no difference whether you're using online or offline maps, as far as the snapshots go.  If it's broken for one, it should be broken for all.

The code is in src/maps.c:Snapshot(), and it uses the XpmWriteFileFromPixmap() function call.  It also puts snapshot_thread() into a new thread.  At top of that latter function are these comments:

// Create png image (for use in web browsers??).  Requires that "convert"
// from the ImageMagick package be installed on the system.  At the
// point this thread is started, the XPM file has already been
// created.  We now create a .geo file to go with the .png file.
