Thanks again for the Corona theme - one of the best I've seen! I'm using it for my own portfolio website.
Regarding the portfolio: I've found that the first featured media upload doesn't always make the best "thumbnail" on the portfolio page. I am wondering if there is a way to use an image for the portfolio page that does not appear when a user clicks through to that portfolio item.
One example: http://themeforest.net/item/artisan-creatif-a-wordpress-portfolio-theme/full_screen_preview/299934 (Here you see images that don't actually appear "as-is" when you click through to see more about a specific project.
Thanks in advance!
