Yep nice overall design, just a few points for consideration:
Don't change the mouse pointer, this annoys some people. Only use the pointer (hand) if absolutely necessary.
Also, sort out the widths. Centre the content, and on 1024 width screen there is a horizontal scrollbar that could be removed by just making things a fraction thinner. Why not set the background width to 100%.
Looks like you put a disable right click script in. Well it doesn't work for me (in firefox), and most people consider these to be pointless/annoying. You cannot protect your content like that.
Why not put your images on this host instead of photobucket?
All your links need not be absolute (full http:// address), this can make things difficult when moving things around.
You say: "Most of the original images/videos of animals do not belong to us."
Be careful, make sure you own the copyright for anything you upload, or you could get into trouble with the terms and conditions.
Like I said, overall, pretty nice design. Well done
