I just learned that WordPress does something peculiar with images. When I upload an image it is associated with a permanent link:

The image then gets converted to a standard size (1024 x 768 px) for embedding in the galleries that you see. The gallery will contain a thumbnail version and if clicked will take you to the compressed version. If you right click this image you can select “View Image” from the dropdown:
From here you will be taken to a url like this:

If you want to look at the original image (for instance in the case of all my high-res seed pictures) then you just need to truncate the extension to get something like this:
