Advanced questions *_*

1) I’d like to display most popular posts in next view:
– number of views
– category
– title
– number of comments
– excerpt

Any ideas how to do that?

2) How to display thumbnail near the post title exactly in category?
3) On main page i display 1 post as image (via custom field) But after that i need to display more 2-3 posts from the same category. So i make the query but it displays post with custom field too (duplicate).

Is there any way to add check like if custom field enabled then display as image, if not then display the rest of the posts but those which are with custom field?

Or maybe another way to prevent duplicate?

4) I’m also searching for an advanced plugin which will open images in popup.

Thanks for patience.
