Welcome!
I get the hi res images from my clients and/or their photographers. I always ask for the highest resolution that they have in order to create the site.
ICQ - yeah, I know it was pretty popular 10 years ago. I still have my same number from years and years ago, while most people with smaller numbers bought it off ebay. It's something you have to get used to - in order to do business in this industry - you need icq.
Good luck!
