This has always perplexed me too. After seeing your frustration I decided to investigate the issue.
I may or may not be right on this. But what I noticed was that this forum seems to paste all photos in a horizontal orientation. So if we take no photos in vertical format, we'll never have the sideways issue. I love to take vertical photos, but I'll just have to remember to do horizontal if I want to post it on TSB.
If I am wrong about this, somebody please let me know.
Your squirrels are adorable!
