I'm not sure if your post deals with how slow the site loads (I have cable
and it was slow), or with the content of the red circle on the screen shot.
The site may be so slow because the DocType you use is English, yet you have
code in your HTML that is not English. This is just a guess, but the "EN" at
the end of your DocType at the very top of your source code stands for
English.
Your graphics seem to be OK as far as size goes. I didn't see any that were
huge files being displayed at smaller sizes, something that will always slow
down a site.
If you intended me to notice the circle and the resulting larger file size,
note that the type of compression selected is for "documents", not web
pages, yet still weird. I use Photoshop to optimize my graphics for the
Web.
