Good to hear that all serial numbers match. As far as photo size goes, I have found that 650 pixels wide fits our screen size so we don't get the slide bar to move it around. Unfortunately, our forum does not have an automatic adjust for the size.
If you decide to use out "Attach:" option, you will also need to bring down your Resolution to about 75 pixels per inch. I notice your photo is at 275 ppi now.
Anyway, good stuff Tim and great to hear from you. Stay in touch.
