Yes, it does sound as though the image may be too large.

I don't really know how the wireless drivers work in any great detail; I
reverse-engineered them from the Linux kernel drivers.  Basically, I
traced all the function calls within the drivers and used the trace to
reconstruct the sequence of operations necessary in order to initialise,
transmit, receive etc.  It's quite possible that I missed out freeing a
resource somewhere, in which case a large image could hit a resource
allocation limit that smaller images just don't trigger.
