Well, you only need to tell if the file exists if you care about that.
In dev, you may not. Try something like:
def wrapped_image_tag(image_name, options={})
image_name = 'placeholder.png' if `hostname` =~ /local/
image_tag(image_name, options)
end
You may wind up with a page of placeholder.png's but it'll be real
quick.
