Simple plugin allows replacing headlines by unique images. Just upload, no sIFR, no Cufon. Plugin is based on http://wordpress.org/extend/plugins/headline-image/ plugin originally written by Pavol Klacansky.
Usability is one step above now. The fact that you must upload image and then go to Media tab to find the image in order to use it as a headline was annoying. Now it is past, upload and use! No unnecessary steps.
