Pdf resize less than 100kb

I get pdf resize less than 100kb error message like “Video not available, cannot find XYZ decompressor”! I receive a save error message. Why are some edit menus or the red eye menu greyed out?

Why is the saved JPG file much bigger than the original JPG file? How can I create selection with exact size or ratio? How can I insert another image into the current image? How can I fix that?

How to extract images from the EXE Slideshow? How can I load only desired file types during the browsing? Problem: If I decrease the color depth to 8 or less BPP, the saved JPG file is always 24 BPP? How can I load file types WITHOUT any extension during the browsing? How to print only a part of the image? How to print many images on one page?
