Try downloading the (free) Crappie.com app and post your pics from there.

Though, I'm not quite sure why your picture leans to the right, when most "tilted" pics normally lean to the left.
In any event, some phone pics will lean to the left because the site does not recognize the orientation code and tries to correct the orientation by turning it 1/4 turn (from portrait orientation to landscape orientation). This is likely the result of constant updates on the site & phones and them not being in sync ... we just don't really know, but that's the most logical explanation.

You can always post your pics in the Testing Area forum to see how they'll appear in your postings. That's what it's there for, and I use it exclusively for all the pics I post. It also doubles as a hosting site, so you can always go back & copy/paste pics from there to present or future posts.
