I'm preparing a GWT batch upload from Europeana of old photographs in the Lithuanian Art Museum. The 470 PD images are viewable here: http://europeana.eu/portal/search.html?query=*%3A*&rows=96&qf=DATA_PROVIDER%3A%22Lietuvos+dail%C4%97s+muziejus+%2F+Lithuanian+Art+Museum%22&qf=RIGHTS%3Ahttp%3A%2F%2Fcreativecommons.org%2Fpublicdomain%2Fmark%2F1.0%2F*&qt=false
A specific example of an image cataloge page on their website is: http://www.limis.lt/greita-paieska/perziura/-/exhibit/preview/20000012645638
And the URL for that specific jpg is: http://www.limis.lt/limisk-portlet/exhibit/resource/image/getByDO/20000012645638_20000012645645_L
