Brian, there's a couple of issues that are causing your pics to show
up sideways, etc.
One is the image size..two of your pics are near 5MB in size..
no need for that size of image for regular use. The images are
roughly 4000x3000 pixels, and all you need for on-line
use is 1000x800 (or thereabouts).
Your camera's software can make many adjustments to an image.

You're probably set at the largest image size, and if you change it to
a smaller image size you probably won't see a bit of difference in image
quality, and the file size will be greatly reduced.
This image was 1.6MB, and it's now 916kb:
This was 4.94MB, now 864kb:
This one 4.7MB to 730kb:
You can also resize images very easily in Paint.
Nice displays...lot of work involved!
