from time to time you want more than just the name of the author to display in your new theme. here is a list of the best authors related plugins for WordPress.
Allows a user to associate a profile photo with their account through their “Your Profile” page.
This plugin does the same thing as the the_author tag, displays the author name, only this time it’s linked to hidden layer (div). By clicking on the author link the hidden layer(div) pop’s up with author info gathered from the profile page, plus gravatar photo (if author email is assigned with one).
This plugin will show the last X posts by the current author either at the bottom of every post, or where you manually specify in each post. Using the built-in options page, you can choose the number of posts to show, set the header text, choose to show the post dates, select the format of the date, and choose whether or not to include the current post in the list. Other options have been added since the first release.
This WordPress plugin lets you create custom permalinks for author pages.
