displaying additional widgets in the center column

I started this again because I had to give up. I was able to create a new widget and call it too the front page only ... but I saw no way to locate it on the page. I wanted it below the text on the page but could only get the top. I also had to call a widget number greater than 3 since that seems to be used by the system

The ideas was to insert a widget that show snippets of different page info, possibly with a thumbnail foto. Someone that posts here has a similar plugin but I can't find it
