Photo suggestions?

[venta]

If I have any spare time this week <SFX: hysterical laughter>, I might get round to putting my photos from News Zealand, York and Orleans on-line. Only I've never done such a thing before, and have very little idea how one goes about it.

I have some webspace, which I think will be sufficient to put a few photos on, but I've no idea what software I want to go about using to make things nice and thumbnaily, and easily viewable.

Any suggestions?
