Example, if I have URL to particular image like (which doesn't exist on server):
domain.com/news/12/imgname.jpg
and i need to generate it on the fly and display it to the end user, i'll use some htaccess to rewrite previous url to:
domain.com/image.php?img=12/imgname
My question is: Will image imgname.jpg be indexed by the search engines (image.php in this case will return always the same image generated on the fly)?
