Error message is misleading

I've installed the g2image plugin for tinymce, and I'm trying to use the Gallery module to configure it.

I installed the plugin, and I now realize I had the wrong permissions. Unfortunately, instead of reporting that, the module tells me "g2image does not seem to be installed for TinyMCE mode. Please see the INSTALL.txt for instructions."

The INSTALL.txt instructions shed no light on the matter.

Perhaps that error string should be changed to "g2image can not be found in the TinyMCE plugins directory, or the directory has incorrect permissions. Please see the INSTALL.txt for instructions." or something like that. I would also suggest elaborating in the INSTALL.txt, otherwise people are likely to assume they need to follow all of G2Image's (poor) instructions.

Thanks
