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,
