Since you all are geeking out on graphics , I'll add my two cents on this matter:
It all depends on the resolution of your monitor. I have my work monitor set at 800x600 pixels resolution because I can see details clearer. But my other computers are set at a higher resolution.
So when you post a photo at 800x600, the 35% of users that set their monitors to 800x600 will have to scroll to the left to enjoy the photos.
99k is a large size for a photo. I could probably reduce those to at least 15k (including a size reduction) by using photoshop. But not everybody owns photoshop, or even photoshop elements, so no worries.
Thanks for the pics, they DO look great, and I have broadband so no issues downloading them.
