There's nothing much I can provide for you in that case. We'd end up spending the bulk of bandwidth on images, and being an image host is expensive - much more expensive than the kind of data we usually serve, which is mostly text and sometimes downloads, but those are much easier to manage than images that automatically pop upon visiting pages.

If you showed to your parents what you'd be using it for and why you'd need it/that you're not intending on browsing, just using it to store images, that might be an option. Or maybe a friend on PMC can host them for you?
