This is what I use for this site so far:
Hosting: tophost.gr, everything was very fast and smooth. Latest version of WordPress was installed.
WordPress theme: Portfolio Press. After having a look and experimenting with many photoblogging and related themes I decided for this one. I like very much the simple design but also the Portfolio type for posts. The documentation in the site is also very helpful.
Before hosting my own site and started using WP, I experimented with:
- Tumblr. I like very very much the hasaportfolio theme. Both the vertical infinite scrolling and the clean and fact carousel. I wish there was something like this for WP.
Inspiration came from the very nice post: 9 Inspiring Photo Blogs You’ll Love and especially from this one.
