I have occasionally picture loading issues too but usually with only one or two pictures in one post and if I change the site I read the post from it sometimes helps. PeakD, hive.blog etc. I hope you get to see the photos soon.

Mamiya at first was weird to handle as it's big and heavy and as with all new cameras, you're first a little bit lost with everything. But all settings, shutter speed, aperture, are put in logical places and easy to use. That's truly isn't with some cameras, Russian Smena and Lumo cameras for instance. Not very user friendly.
