Hi,
I’m a Wordpress professional.
Your project is very interesting for me.
I had a look at your site, below are the comments to your tasks:
Fixes
1. It seems like you are using Elasticslide for showing sliders, but it’s being used not really correct, that’s why you have problems with showing navigation arrows
2. Yes, this is possible, here maybe we’ll have to rework php data selection.
I also noticed that you site is pretty slow, I can help you with this (caching).
Couple of questions:
Would you like to add some more interactivity to your website? For example sharing photos to facebook, twitter?
Would you like a flickr integration?
Thank you
