Screenshots Each theme must export three screenshots, used to select theme in the GUI. First screenshot demonstrates the "index" page, second one the "thumbnails" page, and thirs one the "image" page. To keep a correct ratio between themes, to do your screenshot, first resize your browser so that the webpage will use a rectangular area of 800x600, and use appropriate images sizes (most probable "small"); then resize it to 192x144. It would be best if the screenshots would show the same contents, so just send me your theme if you create a new one and I'll do the screenshots.
