The function documentation string for defimage says this:
Each image specification in SPECS is a property list. The contents of
a specification are image type dependent. All specifications must at
least contain the properties `:type TYPE' and either `:file FILE' or
`:data DATA', where TYPE is a symbol specifying the image type,
e.g. `xbm', FILE is the file to load the image from, and DATA is a
string containing the actual image data. The first image
specification whose TYPE is supported, and FILE exists, is used to
define SYMBOL.
I am trying to narrow the problem down so that I can either patch it
or give a better report.
Nic
