# Returns an image tag converting the +options+ instead html options on the tag, but with these special cases:
#
# * :alt - If no alt text is given, the file name part of the +src+ is used (capitalized and without the extension)
# * :size - Supplied as "XxY", so "30x45" becomes width="30" and height="45"
#
# The +src+ can be supplied as a...
# * full path, like "/my_images/image.gif"
# * file name, like "rss.gif", that gets expanded to "/images/rss.gif"
# * file name without extension, like "logo", that gets expanded to "/images/logo.png"
