Can Anyone Give Me Advice On Posting Photos?

Taking pictures is more than an AP or camera although both help. You need to know how your camera works, it has to be framed correctly and then you can resize to upload here. But don't feel bad vast majority of people take really bad photos just look on any social media site or even here.

Sorry I can't help you take better pictures, that's on you.

theres cheap coin microscopes that have built in lights on them for like 20bucks its a start id say. Theres your phone clean your lenz and lighting and angle steady hand snap shots. Hope this helps... Also take about five shots full coins and specific relevant focus points. choose the best pictures more than one of the same thing with different angle is good but can take alot of time just dont obsess over it unless its requested.
