So what is your question?

Function
to remove all classes on images

I’d like my images to have no classes assigned to them by default.

img class=“alignnone wp-image-15 size-medium”
change
img class=“mycss”
and remove default img width=“300” height=“225”, I want without width, height
example tag
img class=“mycss"src=”/" alt=“/”
