http://photobucket.com/ is highly recomended but you would have to create an account. It's free of course.
for very fast results you can use
http://www.mypicx.com/ (or many other sites; there are millions if you google) .
After uploading your pics you can
use [IMG ]the url of the pic[ /IMG] so they appear here
or
just post the link so we can visit an external site.
I am so much into the inifity's you bought. Have you considered the JL Audio C2-400X? Same price range but I do not know anything else (there were recommended by a friend)
