So, recently (not entirely sure when... something in the last 2 years) the code for images was changed, so that they could be viewed in a new window, by clicking on the image.

Additionally, by adding an "s", "m" or "l" to the end of the imgur filename link, you could resize the image in your post, so as not to overload your post with giant images, or to blow up smaller images as necessary.
However, I have found that even the link remains the same size. (If I make it small in my post, it's small in the new window). And, in addition to that for me adding "m" is not a "size" category (it doesn't change the image size).
So, what are the size "codes", and can I make it show a resized image in the post, then the original in the new window?
