Subject: [PATCH] elementary image: don't calc size using empty ones.

Summary:
Zero-sized image occasionally happens.
That occurs insane img/clipper region.

bj size => (w, h) then resize => (0, 0)
file_set(xx.jpg) then file_set (NULL)

Because of this, region could be flickered during prev/cur preloading images.

@fix
