Hi Gary,
Thanks for your reply. Apologies if I came off rude at all with my OP. When I said the plugin did not behave as expected, I simply meant that I had probably not bothered to configure it properly – it added the bios to the home page posts, which was not what I wanted.
My actual aim was to have the 2 plugins work together in that the twitter avatar would be in place (as it was) and then I could use your plugin to add more detailed author info such as twitter URLS etc.
I believe the add local avatar plugin is fairly old and the support forum is something of a wasteland, so I daresay the plugin makes use of some deprecated functions (my WP is up to date).
I have not managed to sort out the problem, so gave up and am currently using the ‘Mystery Man’ avatar and a simple bio provided by my theme.
Perhaps you could add twitter avatars to this plugin ??
