Which set of instructions did you use? There are several in that link I provided. You just need to root around to find the right instructions for the systems you use.
I'm no help to you, given i still use firefox, and xp, I resize using paintshop pro, which is probably too old for what you have. It's the only one I can operate.

just click on the envelope under my username, we can get into email contact then, you can send me the originals and I'll resize them for you.
