Answer myself: should be solution before
Start.get().getSharedResources().add("image" + random.toString() + ".jpg",
image);
do something like "unmount all previosly mounted images"?In Application.init() isn't possible to mount them - I don't know which page user click. In database is around 1.000 images and there are on around 100 pages (every page has around 10 images). For me it looks crazy in Application.init() take all images from DB and mount them. > -----Original Message----- > From: Miroslav F. [mailto:mir...@seznam.cz] > Sent: Friday, 05.
