## Get the filename of the selected file.

## Check that the selected file is a 'gif' file.

##################################################################
## Make a filename for the text output.
##
##    If the user has write-permission on the
##    current directory, put the file in the pwd.
##    Otherwise, put the file in /tmp.
##
## On second thought, to avoid junking up the 
## current directory, ALWAYS put the file in /tmp.
