symfony's image_tag(): Handle With Care

Turns out, symfony's image_tag() helper is a sucker for memory.

It takes more than 34 megabytes of memory to render a page displaying a list of about 500 rows, each accompanied by a set of four or five icons, each icon's <img> tag created by image_tag() helper, with additional parameters provided like this:

image_tag("some_image.png", "alt=Lovely, title=Rita")

With those images coded explicitly, rendering takes just 8.5MB. A leak, maybe?
