When you upload them, it lets you set the alignment (left, centered, or right aligned). I had struggled to get the alignment right when I'd upload photos from Flickr.

Here's a photo I took with my camera phone on the way to work. I remember in Minnesota when I'd go into a flower shop to buy flowers to make an arrangement, flowers such as this were too dear for my budget. Here they grow everywhere. Notice the snail making a breakfast of the flower; I hadn't seen one so far out of its shell before.
