Since the images on the subdomains would be linked from the main domain, Google will certainly be aware of the subdomain and will certainly grab the linked images.  I don't believe you will get the subdomain actively crawled as a separate entity, though.  The algorithm is smart enough to detect that you are just serving resources off the subdomain instead of actively hosting real content and index accordingly.

CName for static images - will Google crawl?
Like in title, can I somehow get size of dynamic allocated array (I can't keep it separately), or somehow loop through this array without using it's size?

int *ar=new int[x]; //x-size of array, I don't know it in the beggining, 


P.S. If I wanted to use std::vector, I wouldn't ask about it, so don't tell me to use it :)
