To me this looks way too overcomplicated. I suggest a simpler approach: 1. mw copies a placeholder image to the appropriate filename: the placeholder could be the original image, best match thumb or a PNG with text "wait until the thumbnail renders"; 2. mw send request to daemon; 3. daemon copies resized image over the placeholder. _______________________________________________ Wikitech-l mailing list Wikitech-l@lists.wikimedia.org https://lists.wikimedia.org/mailman/listinfo/wikitech-l
