I have a strange problem. If insert a gallery shortcode into my post, a gallery is created, but broken. All classes say thumbnail, but the actuall image sizes of the images used are full size, not thumbnails.
The problem can be seen here http://www.delikatesy.sk/cestujem-ochutnavam/fotoreportaz-jar-v-banja-luke-6954
I am using WP 3.1.3 and slightly tweaked TwentyTen theme. Recently I was rebuilding my images (adding some extra sizes), but did not touch or change the thumbnails or their sizes.
thanks for any answer.
