You need to upload the photo file. Just keep in mind that the best format would be jpeg and the file size cannot exceed 100k.........any problems let me know and I will guide you
I do not know the Nikon view...........I would change it to jpeg, resample to 640 x 480 and then look at size........it the file size was too big I would change the compression ratio to get the file size just below 100 kb.
I do the same as Kris... Size it for viewing then compress it to fit. I use Lview, only because it's a habit for many years, not because it's the best...
