Regarding compression, I believe lzma is already builded in the wikireader application and it compress the images a 50%. enough for start I guess. but I have to recongnize than the image on png looks really good do maybe it worth the meaning to implemente it on the device if it's not much resource hungry
Regarding licensing , well until OM or/and Wikipiedia doesn't say the contrary (for example considering Wikireader as an extension of the Wikipedia and allow all wikipedia image to be on Wikireader) we must stay in the save side so only explicitly free licenced images will be safe to use, I'm working on the http://download.wikimedia.org/enwiki/latest/enwiki-latest-image.sql.gz table to know how many pictures we are talking about. Also some way to not infringe the authoring and licencing text includings clauses must be used by the images viewer. but I guess it can be done by links to text as other wikipage more. Regarding machine needed to do so, due we just need at maximum of 240 pixel with we can tweak the Wikix to use the thumb url like this http://upload.wikimedia.org/wikipedia/commons/thumb/f/f9/HN_Pegasi_B.jpg/240px-HN_Pegasi_B.jpg instead of the full url http://upload.wikimedia.org/wikipedia/commons/f/f9/HN_Pegasi_B.jpg and this will save us a lot disk space and a step in the process :P Also Wikix must be tweaked to just download "free licenced images" using the info on the enwiki-latest-image.sql.gz file then sure we will save a lot more disk space.
