If you have the free flickr account it's probably going to resize them 
to 640x512 maximum after you upload them whatever size you crop it to.

In Photoshop you can create a crop tool preset for 11 in wide at 72 dpi.

Using that tool, just drag the crop box until it surrounds the whole 
image, and hit <Enter>. Save it as a jpeg and it gives a 792w x 528h 
landscape image for the web.

You don't set a vertical dimension.

But, you can use the swap button in the middle to switch between 
vertical and horizontal if you should need a 528w x 792h portrait 
orientation.
