Files password protection on Sony Ericsson?

I have Sony Ericsson g502.
My friends just always want to explore my phone a bit, which is okay if they
want to send music or something.. One thing i really hate is that i don’t want my friends
to view my photos but there isn’t a way of hiding/protecting them on sony ericsson.
I can tell them to not view my photos, bud i don’t really trust all of them because they get even more curious when i say DO NOT.

I can either pull my memory stick out when giving them my phone or just backup my photos on my
computer. Both of those are not the best things to do because if i pull out my memory stick, there won’t be no music on my phone so they won’t be able to send it and if i backup the photos on my computer, it will be hard to put them back every once in a while.

Is there a way to hide or password protect my photos on Sony Ericsson?
