It was reported GPT 0.7 was not working with new WP 3.1. Apparently, there were some changes in jQuery versions in WP. So I updated plugin to 0.8 to support this, and tested so it’s now working with WP 3.1.
I also added couple of convenient features people asked. First is Live Log. You can see log of all successes and failures, as if the file was taken from post body or uploaded from external server and what caused the problem. And second, you can now remove all featured images by clicking on new button “Remove all featured images”. Also thanks to Andrew, I added rawurldecode for externally hosted images to minimize problems that may occur with images which contain non-english characters in filenames.
I added a notice and I want to remind again, please, don’t forget to backup your WordPress files and database. Although this plugins saves you lots of time, if you have many posts you want to assign Featured Image to, it performs mass manipulation, by changing posts Featured Image property and uploads first images if they are externally hosted.
