-------------------------------------------------------------------------------- So I have a blog and I post 2 different things. One is strictly pictures and the other is strictly stories. When I post now, its posts both pictures and stories. Both come up in the main page. What I want to do is post stories and not have pictures show. So I post a story, it gets shown on the main page. I post a picture, it doesn't get shown on the main page but it is shown in a link I have.
You will have to modify your theme to exclude the Picture category inside the Loop that lists all of your posts. More information at The Loop in the WordPress Codex.
I just did something similar to this on a blog site I created. Now my them framework app makes it easy to simply exclude category ids from the main page, but I actually created all kinds of links to specific categories. You can use Appearance > Menus to make a custom menu with links directly to a category, even menus with both pages and categories mixed. So one category to the picture posts and one for the non-pics. PM me if you are curious about the framework program I use for building themes because I don't want to spam here, but it kicks *ss.
The solution is you need a plugin which filters it out. I don't remember the plugin name but it works and keeps them filtered.
