Database Scaffolding and Photos question? Kinda lost....

[eluser]generalsalt[/eluser]
I'm pretty new to CI and mysql and have a question.

I am attempting to make a small portfolio site for myself, complete with titles, description and photos.

I am using CocoaMysql in OS X to create my database, pretty much following the blog video tutorial on this site.

I'm using the scaffolding feature to add descriptions and titles to my MySQL database, and that all works great.

My question is what do you do when it is time to add photos? I guess MySQL doesn't 'add' photos themselves but just the URL locations? Is this right? Honestly, I haven't a clue what to do when comes to this.

Ultimately, I'd like to be able to have a browse/submit button to upload photos to a folder of my choosing and have it do whatever (??) to the database so it updates.

Can anyone educate me a little on what to do here?

Thanks!
