Rule of thumb that I was taught for sizing is, that if it fits relatively well with 100mm of seat post out of seat post tube and 80-100mm stem length then from there it is just adjustments of seat height and stem length to dial in perfectly.
As far as pics go, are you loading from your computer or device or a Photo hosting website?

I have only been able to load a single photo from my iPad but can load 5 with ease directly from my computer, simply click Go Adavnced at the bottom of the box you are typing in and then scroll down until you see Manage attachments and go from there, and as the guys are saying drive side pics(other side from the pics you have done) outside or against a light background will help us Eagle eye folk point out the good and not so good

Welcome to C & V hope you enjoy it a good bunch on here that will help where needed.
