Why do I look different when I take pictures on my iphone horizontally and vertically?

So I realized that every time someone takes a video or a picture of me, I end up looking really short (though I'm already short to begin with) and my legs look very chunky and look less like they do in the mirror. But if I take a picture horizontally, then everything looks kind of proportionate and more importantly, my legs are a lot more nicer looking and slimmer.

Is there really a difference between taking pictures horizontally or vertically or is it just me?

Will my iphone pictures go to other iphones?

I just brought an iPhone from a mutual friend & his icloud was NOT still logged in or anything but he had the phone before me. So i was just wondering will the photos i took or take be able to go to any of his apple devices or any devices if he tryed to get them? Like could he still use the imei # or something? I turned my photo stream & icloud sharing off but i was taking pics before i did that. I deleted some but from my understanding, deleting a picture won't delete them from the other devices unless you do it manually. But is it possible for him to actually get them on other devices if my icloud is the only one on the phone? He's kind of a creep so i just wanna make sure he couldnt get to them without my icloud. I know this sounds weird but i know nothing about tech stuff. I tryed to look it up but of course i found no answers relating to my situation

I pressed Erase iPhone on the Find iPhone app?

I pressed Erase iPhone on the Find iPhone app and it deleted everything I had on my phone and I took it to T-Mobile and they said it can't be fixed. Is there any way to get my pictures, contacts and more back. I didn't have iCloud so that is an option

I forgot the password to my iPhone 5 and it won't connect to Wi-Fi?

My phone restarted on it's own one night and so when i looked at it in the morning i forgot my password since i usually use the finger print. The Wi-Fi and cellular data turned off for a while but it is back on today. I'm trying to restore it on iTunes but it keeps saying an unknown error occurred since it won't connect to Wi-Fi.
