I’m with Kaknu on this one. I tried Gallery and it was horrendously bloated. Gallery was like trying to crack a nut with a nuclear bomb.
I then tried Lazy Gallery, which was quite nice, but if I remember correctly it didn’t have database capabilities, so no comments. And I don’t think you could put captions in it either.
Plogger’s definitely my favourite and you can customise it quite a lot. My only gripe is that I can only get it to work with my default WordPress theme and none of my other themes, but seemingly the latest version of Plogger (due out in the next couple of months) will sort this out.
You can drop thumbnails into WordPress posts so when the reader clicks on the thumbnail to enlarge it, it goes directly to the Plogger photo page, which is integrated into your main theme. So, in effect, you never have to leave your “branding”, as it were.
Plogger is really, really easy to set up, use, and customise, and the guys in the support forums are dead helpful too. I think it’s brilliant!
