How to direct upload image/text to webpage from cellphone?

Hi there

Does anyone know of a way to upload an image/text directly to a webpage from a cellphone? iPhone, HTC etc..
I have a forum for friends and I thought this would be a cool way to keep the other members updated.
The page is written in asp/vb, Dreamweaver with an Access Db.

I have seen this done in other solutions linked to twitter, facebook etc, but can this be done fairly easy on a personal page?

A kick in the right direction or views on this topic would make me happy :)

Regard,
Christian
