Pre-Sale question - different hosters

I'm running vBa CMPS v2.0.0 and vBulletin 3.5.0 on the same webspace/server and same hoster.

Now I have another cheaper hoster with more webspace/bandwidth. Is it possible to install vBadvanced Gallery together with vBa and vBulletin on the same server/hoster but storage the images on the other hosters webspace/server?

Example:

Hoster A:

- vBulletin
- vBa
- vBadvanced Gallery

Hoster B: (different server/location)

- only storage the images from vBadvanced Gallery.

I'm sure it's possible, but there are no default options to allow it to be set up like that. I've never looked into doing that either, so I'm not exactly sure how much work would be involved to set something like that up.
