Hi Tenzin,
See attached screen shot made with firebug extension.
It took 8.79s to load 130 KB image. Try reducing image quality or correct colors, it will help loading faster.
Also, look at very bottom line:
29 requests - 413Kb - 16.5s
You're smart girl, I think you know what to do
Good luck,
P.S: Will find yammy extensions here:
