OK - 2 things.
- What format does the photo need to be in when uploading to the SDMicro card, and
- What is the maximum resolution that uploaded photos can be
I was unable to find any of this info in the PDF of the User's Manual, or in any of the paperwork included with the phone. I inserted this photo into the "Photos" folder of the SD card: "Paper-Background-8_small.png", and it is 1.00 MB, with a resolution of 1080 x 1526

When I go to "My Pictures" in the phone, to look at it, I see this:

So this brings me back to the first part of this - is there a specific format the photos need to be in? If so what is it? Also, what is the maximum resolution that the photos can be?
