Hi all,
This is a preliminary list of what needs to be done to generate images dumps. If anyone can help with #2 to provide the access log of image usage stats please send me an email!
1. run wikix to generate list of images for a given wiki ie. enwiki
2. sort the image list based on usage frequency from access log files
3. download images over HTTP
4. scale images down to desired thumbnail size
5. tar image collection into multiple tar files (first tar file has the most commonly used images)
6. post to Wikimedia image dump or bittorrent
cheers, Jamie
