For performance and reliability (the problem you are seeing is almost certainly the result of memory management trouble) I would create an actual 75x50 pixel thumbnail (not shrink a 5 megapixel image) for the opening page and link to the full image as a discreet file on disk.
- Loading multiple megapixel images is sure to gobble up tons of RAM - Keeping images on disk preserves ability to work with graphic apps easily, as well as Windows Explorer thumbnails, etc. - Keeping images outside of the stack minimizes potential for corruption Bill "Rob Cozens" <[EMAIL PROTECTED]> wrote in message news:[EMAIL PROTECTED] > Hi All, > > I have a stack displaying my wife's artistic creations. > > The basic design is: > > Title Card > About Card > Art Card 1 > ... > Art Card n > Photo Index > > Each Art Card contains one to six 5MPix jpeg images locked in 75x50 > "thumbnail" size & position.
