I was able to load it here.
The site is attractive and scales well across different browser/display sizes and shapes. You did a great job with that.
I do see some problems that will make the site unfriendly to users and search engine page ranking, though.
From an implementation perspective the URLs are sort of goofy. Is there any way you can eliminate the Camera_Focal_Point/ prefix to all the URLs? Would be a lot better for search engine page rank if you moved the sections to their own index.html (or equivalent). I think you'd be a lot better off switching to something along the lines of:
http://camerafocalpoint.com/
http://camerafocalpoint.com/wallpaper/
http://camerafocalpoint.com/guides/
Trying to eliminate any Filename.html that bleeds through.
Having mixed-case filenames in the URL, while technically fine, looks bad to me too. I know it's a tiny nit, but there will never be an easier time to address that sort of layout and framework concern as you have right now.
I notice that the URL is the same for page 1 and page 2 of the wallpapers. That's bad because it prevents users from being able to link to a specific page. As I navigate around the wallpapers and back to the grid the Location in my browser can get desynched from what I'm actually looking at.
I think that the individual pages for the wallpaper browser should be referenced by unique URLs since they represent distinct content.
When viewing a specific wallpaper image, the thumbnails do not consistently work. Only some of them are clickable to jump directly to that image.
As you expand the site to include more textual content (presumably under tips and guides) you may find that the white text on the gradient red background is hard to read. People will probably want a higher contrast style for text information. I hope you have a plan for that design as well.
I'm guessing you're also dissatisfied with the relative disconnect between the "real" site and the forum too. That's always a tricky one to solve, but worth the effort in the long run. The less connected the forum feels to the actual content of the site the less likely users will be to use it.
Site loads fast for me. On the whole it looks like a good start.
Edit to add:
"To download wallpaper, double click on the picture, and hit “download.” is an inaccurate instruction. I assume you mean "right-click" not "double click."
