I usually just use GNOME System Monitor. It displays that information under the “Writable Memory” column. You can also do it yourself by inspecting /proc/(pid)/smaps: sum up all the Private_Dirty fields. Finally, there’s a Perl module called Linux::Smaps for querying this information.

Hmmp! Happened to me too. Oh well. After you paste the (complete) URL into the URL field on your browser, replace the “×” in 300×200 with a proper lower case x character. (Or hit Enter to see it converted to %D7 by the browser [firefox, anyway] and replace that with a lower-case x).

Somehow your “x” in the size got converted to a “times” character. Try:
