I'm not even sure that will make it display the way you want. Websites pay for the "room"/space that is used and how it is used, in addition to what additional tricks the host allows.
By "how" I am referring to "bandwidth". When you post a picture from one place to another, let's use one of my sites as an example:
Code:
http://mysharingspaceonline.com/angeldevil.jpg
gets you:
I am posting that picture from mysharingspace.com on here but, you are looking at it AT mysharingspace; it's kind of a "reflection" if you will. Everyone here at PC is actually using my bandwidth that I paid for when I bought mysharingspace.com from GoDaddy. Notice the different prices/sizes of space/bandwidth one can buy.

If you have a lot of traffic to your site (and your looking at my picture here on PC is actually looking at the picture on my site because it is there, not here, so the site gets credited for bandwidth use, not PC) sometimes web hosts will charge more or make you have a bigger site. That is why free web hosts will often not let you link your pictures from their site to somewhere else, one will get the red X, they don't want to be paying for your posting your stuff all over the web for free.
PC doesn't have that problem, because it has its own servers. It does not just own the site, it owns the hosting, the space itself and can do whatever it likes. However, how many/much server space it owns is limited; server space and setup costs money too:

But what happens on PC, depends on its programmers and how the software is written. It could be "simple" and just accept what you upload and, you're done, or it could let you mess with it; look at the controls for customizing your profile:

I don't know/think that what you do with pictures is given that much control. When you upload a picture, it might just want it at a certain size (look at avatars and their control size) and no matter what you do with it on your computer, the PC software will do its own thing, show it at a size it wants.
Since I'm not using PC as my "host" for my picture, the PC software often doesn't care what size I make something because it doesn't really have anything to do with them. Yes, they prefer I don't post something too big, because it skews people looking at it, and can make the PC software go to extremes to display it at all and distort other things, but since it's somewhere else, they generally don't care.
