Great post!
I can see it becoming quite huge.

The first number is the width (in pixels). The second is the height. For ATP, the maximum width that will be displayed is 1000 pixels. So when you upload a photo, it shrinks it to 1000 pixels wide and adjusts the height proportionally.

The 13.2mb is the file size. How much space it takes on your hard drive - and how much info is in the picture. If you were to drag an ATP photo to your desktop, you'd notice that the file size is significantly smaller. The one I'm looking at right now is 1/2 of a megabyte.

One thing you can do to save yourself some time and frustration on the uploading (as well as saving your bandwidth and Dave's) is to save a copy of the picture at 1000pixels wide. Most photo editors and even some viewers have the option to do it. Just make sure that you don't overwrite the original picture with the one you're trying to shrink. That would be (and has been) tragic.

The other thing to take into account with photos is their resolution, how many dpi (dots per inch) or ppi (pixels per inch) the photo is. Your camera will probably have a setting to take photos with different 'quality' settings - high, medium and low at a minimum (this is usually the resolution). The higher the resolution/ quality the larger the file size but you will be able to blow the photo up to a larger size with less loss of quality. Conversely at a lower setting the file size will be smaller, and you'll fit more photos on your memory card, but when you try to enlarge the photo it will start looking fuzzy quite quickly. Computer monitors use 72 ppi as the default so posting a high res image on the net will cause it to look unexpectedly massive - you are best to display the image at the size you want at 72 dpi. For print quality (like publishing), they usually require a minimum of 300 dpi (not ppi).
