Hi Andrea, You need to do some maths on how much data you have... it's pretty obvious that unless the images are tiny you'll never be able to load 15000 jpeg files in memory at once. The *only* way you can do it is by reading the data on demand like a video - such as what the xine and qt plugins do, subclassing from osg::ImageStream and then providing a background thread that does the reading of the images.
