image_tag() has :size option, but only takes height/width parameters. i
want to be able to scale down the image by 50% because all my images are
different sizes so i cannot be specific as image_tag() wants me to be.
is there another RoR method i could use.
note: i don’t want to resize my original images, i just want to be able
to display them %50 smaller. hope i make sense.
btw, great forum, very helpful!
