Thanks man! I just don't think forums in general are coded for stuff like this. Hell, some of those images full sized are bigger than my old ass square 19 inch flat screen monitor and take longer to load than a streaming HD video. It's absurd to have posted images anywhere on the web that size. Maybe the actual master copies that you keep.
I too am in a business that involves design and hirez pictures for our customers. We shoot our hirez pics with a Canon EOS 5D Markk III at 5760x3840. You know what size we give them to the consumer? A VERY web friendly 1600x1067...and we are a multi-million dollar a year company. Our customers would have a stroke if it took more than one second to load a picture and we would end up with no customers. You also could reduce the actual file size by taking down the image quality setting in photoshop to at least 80%...the humam eye wont even detect the difference and also maybe save the web copy as a .JPEG instead of a .PNG. I'm guessing you also have originals saved as a .PSD as well? One of your 4950x3000 pics is a whopping 2.44
MB's. The pictures we offer our customers to view over the web are an "instant" loading 400ish
KB's...and they are actual photographs.
This is also some coming technology that will help big time. It's a way, through some coding that is going to revolutionize hirez pictures and then GIANT dimension pictures like yours will be more web friendly.

Your work is very, very good but if I may offer you some advice that will get them viewed more easily (afterall, that's what it's all about, right?)...you could focus on file size compression and finding the happy medium of high quality
and user viewability.
