Picture albums broke when domain changed

[Logician]

I dont know why its reading files out of my old domain and not new domain?

You probably solved it out already but I'm writing for people who will have same issue.

When you change your domain, you need to change file paths in your vb options and cache. If you don't vb will use your old domain's paths (eg. $vbulletin->options['attachpath'] variable will be pointing old server's data structure) and when it tries to read from there, you'll get this error. It has nothing to do with open_basedir restriction in your current server.

If you enable debug mode in your config.php, login to vb options, you'll be able to modify these paths in the hidden variables of vbulletin.
