You can do this in IE if you set the height/width in ems, but you will
get a loss of image quality unless you are using a scalable image type.

I'd recommend using a submit button also, but not to use noscript.
Noscript content is not read by JAWS, whether scripting is enabled or
not, so it would be better to use the standard submit button and use
javascript to modify the disabled attribute to be disabled="disabled".
Then, if scripting is off, the button will work (and your data
validation will need to take place server-side).
