Unfortunately, it will always crop the picture, unless the photo you are trying to put is a square. You can move where the cropped square is or enlarge it (if there is enough room to enlarge it). How you enlarge it is by holding on to the biggest square in the bottom right corner and pulling it. Same for moving it but you just hold the middle and drag it. This is for the mobile version and I don't know if this will actually help. I hope you can find a way to fix it! ^^
Of course! (This is for mobile) Click on the three lines on top of the Mangago screen and press settings, which is between bookmark and logout. After clicking on settings, scroll down until you see upload in the avatar section. Pressing upload, I believe, you'll see your photos or collections. Click on a photo you want and it will automatically crop the image you put for you. You can change the size or the area of where you want it cropped by dragging the tiny blue square in the bottom right of the box or moving the box with ur finger. If you have anymore questions, I'll be here!
