HA HA HA HA HA HA HA I was WAITING for you to notice, get irritated by something in the new GAG (which I actually think is the best look and awesome - including the circular pics) BUT you asking something to support and i WILL!!! (((((((*HUGS*)))))))) ha ha ha that's SO cute little lioness - can't do w/o you getting irritated with some change lololol
Though I support you cause it's YOU and voting accordingly, I think GAG can come up with some way of maybe a GAGer being able to resize and move the pic according to their choice :-D
The thing is, that they want to make your pic be able to fit in a nice little round shape (aka your 44x44 pixel image which other readers see next to your opinion). Therefore IF your original picture's height is bigger than the width THEN you'll need to crop it. But only then. What you can do how ever is that you open up you original picture with microsoft paint and add some extra width to your profile pic. For example:
You add an extra rectangle on the left & the right (pink color). Well probably you'll want to choose a different color than pink, for example black. Let me know if that helped.
Otherwise yes, that's kinda annoying but apparently they did not want to develop extra lines of code. They thought it's gonna be fine like that and perhaps they'll gonna release another update later on which will fix the problem. Interestingly it seems that my old pic was added the extra width so all the original pic can be seen.
I hate it too but I guess they tried to make up for it by allowing us to have cover photos. Now, I wish they'd somehow make it possible to view cover photos without having to click on profiles because I've been going though all my follows, followers, and random user profiles just to see their covers lol. Half the people still have the default cover.
It doesn't bother me except for selfies. Like if it's a picture of someone, only their face really fits in the circle which can sometimes look weird. The circles don't bother me that much but I do think I liked the squares better.
