This is an old request that I get a lot of times on my themes. Usually posts are ordered by date so all you have to do is change their date. This might not be the solution, because sometimes you want to display the correct date on the frontend (and for some reason you want another posts order).
Wordpress 3.5 is here and those who are using the great Victor Teixeira image resize script some warnings might have appeared on your Wordpress installation. The image_resize function is still working, but deprecated (in favor of the “wp_get_image_editor” function). This means that it should stop working someday.
Over the last years we created 16 WP Themes and performed hundreds of customizations on Themes and Plugins. We also built a large number of websites for clients all over the world.
