Size limit depends on exact model. Anything over 4GB will almost certainly not work consistently with any. model 1GB or less should work with any model. None of the images should be stored in folders, and all should be jpeg format (.jpg). If any of them have been edited, they may be saved as Progressive jpeg or something similar even if the extension (.jpg) remains the same. If you resave the missing photos in as JPEG in MS Paint, it should ensure they are compatible. You may have to format the memory card and re-add the photos to make sure it will work,
