Your Favicon Displayed For All To See
Yon now should be able to see your favicon via your page tab and favourites / bookmarked. If you have any problems uploading your images then go to Techotronic All In One Favicon Plugin page for more details about the plugin, to check that you have installed the plugin correctly or contact them via email.
I personally have had no problems with this particular plugin and I have four websites on WordPress using this plugin to add my favicons but if you do have problems even with the help then I would recommend just deactivating the plugin and re-installing it again. Hopefully any bugs will be remedied if done that way.
