oh, pshrynk. pshrynk pshrynk pshrynk. seriously, you don't know how to take a screen shot ??? *sigh*.
if you were using firefox it would be the easiest thing in the world (have you heard of
portable firefox, by the way ? runs from a usb key drive, no installation necessary, no admin privileges necessary, which means you could even use it on that ridiculously locked-down and crippled machine they've inflicted on you at work).
*but* since you're using The Bane Of My Existence (otherwise known as IE), what you have to do is press the "print screen" button on your keyboard (it might be called something a bit different... i'm translating my french one). on my keyboard, that is the top left key in the little block of keys between the main keyboard and the numerical keypad, along with the "home" "end" "scroll" "insert" "delete" etc. keys (9 of them altogether).
that will copy whatever is on your screen (*all* of it) to the clipboard. then you open your image edition software, create a new file (which, if it's anywhere close to as good as photoshop, will automatically be the right size) and then paste the image in there. then you can crop all the extraneous bits.
if your cart is longer than the height of your screen (like mine...) you'll probably have to do that twice, and scroll the page down in between.
if you don't even have any image editing software, i suppose you could try pasting it into word...
you let me know how it all works for ya.
