Thank you so much for your usefull observations. But I continued to notice a strange effect, which seems more evident when I load images which dimensions are relatively small or unusual (for example 800x600 px, 850x640 etc...). Once started either preview or exe, image quality appears more soft and smooth than the original files I see in photoshop... I'm sure that the anti-shimmer or blur in Objects and Animations are uncheked, and only if I previously check "low quality resize" button in Objects and Animations I can see images almost whith quality of the original files. What is wrong in my worflow??? original file's crop slide's crop
