You are right, I was over releasing and maybe that was crashing the app.
But still, even without [image release] the memory used by the app on iPhone
is slowly increasing (like 3K for each image display). Maybe that is
supposed to happen , maybe something is cached somewhere.
But the good thing is it did not crash anymore after 200-300 images
displayed.
Thanks a lot,
Dragos
