Thanks!  Very nice update.  I'd been using the original code for a while
but prompting for the file name is quite helpful.  However, if I give it
a directory name, the function fails with "Cannot create image file" in
the mini-buffer.  With debug (note: only function name is different):

,----
| Debugger entered--Lisp error: (error "Cannot create image file")
|   signal(error ("Cannot create image file"))
|   error("Cannot create image file")
|   (if (file-writable-p name) nil (error "Cannot create image file"))
|   (unless (file-writable-p name) (error "Cannot create image file"))
|   (if (file-exists-p name) nil (unless (file-writable-p name) (error "Cannot create image file")) (message "Taking screenshot...") (call-process "import" nil nil nil name) (message "Taking screenshot...done"))
|   (unless (file-exists-p name) (unless (file-writable-p name) (error "Cannot create image file")) (message "Taking screenshot...") (call-process "import" nil nil nil name) (message "Taking screenshot...done"))
|   esf/org-screenshot("~/s/test")
|   call-interactively(esf/org-screenshot nil nil)
`----

In summary, if I give it an existing file name, that works; if I give it
a non-existing file name, that also works.  It only fails if I give it a
directory.

thanks,
eric
