Old structure was even worse because there is 31998 limit sub-directories per one directory in ext2,3 filesystem and there is no limit (or it is very high) for number of files per directory. Now you are talking about limits of the software you are using for browsing, but not system limit.

In the future we will consider structure like this /a/b/c/d/abcd4543564.jpg, it will solve both problems, yours (with software you are using) and filesystem limits.
