Depending on how big your work is (smaller than a normal paper sheet) I'd say try to get a scanner. The quality is much more decent. A digital camerea like you already use works as well though.
All you need, once you have the picture on your computer, is a service to make it available to the internet. One that has been around for quite some years now, but sadly goes slower every day, is imageshack.us
. That of course is only one of many services. If you have your own webspace it'll be even better.
If you need help on how to post stuff here, I recommend you to read our faq, the PEELers' FAQ
. In there all the codes you need are explained, as well as general guide lines on how to get around here.
Enjoy your stay.
