It is better to change the legacy URLs in database level, IMHO. To replace all http:// occurrences with protocol-agnostic //, run these SQLs:

UPDATE wp_posts 
SET    post_content = ( Replace (post_content, 'src="http://', 'src="//') )
WHERE  Instr(post_content, 'jpeg') > 0 
        OR Instr(post_content, 'jpg') > 0 
        OR Instr(post_content, 'gif') > 0 
        OR Instr(post_content, 'png') > 0;

For single-quoted occurrences:

UPDATE wp_posts 
SET   post_content = ( Replace (post_content, "src='http://", "src='//") )
WHERE  Instr(post_content, 'jpeg') > 0 
        OR Instr(post_content, 'jpg') > 0 
        OR Instr(post_content, 'gif') > 0 
        OR Instr(post_content, 'png') > 0;
