A few things you should consider changing (imo):
- The icon-navigation on top would probably look better if you put the icon-text
beneath the images, not to the right. That way you could place all your icons in one row only. The up-to-date news icon looks a bit lost now...
-
http://www.iphone-hackers.net/iphlickr.html features an image that has been resized via HTML img-attributes. It’s distorted, because the original image is much smaller.
-
http://www.iphone-hackers.net/web-apps.html features thumbnails that are also just resized via HTML, instead of using smaller versions of those images. Apart from taking more time to load, it also looks kinda ugly if you minimize pics via HTML.
- I’d make the site-title, and perhaps even the whole top-left img-area a home-link as well. That’s usually where you’d expect a "home" link to be, it has become an automatic thing to do for a lot of people (logo = home, or "top of the category").
- I’ve noticed that a few pages don’t use "friendly URLs". I’d use the same URL schema for all pages (either FURLs all on or all off). You probably forgot to add an alias in some pages.
- The sitemap link just goes to the frontpage; I don’t see any sitemap at all.
