troubleshoot my drupal installation

i have a drupal installation that is not showing pictures in page view, whether i'm logged in or not. it inserts into my wysiwyg editor fine, and displays there, but when viewing the page, the image does not show up. it displays images if i add them as an image post (all by itself), but i can't get it to display when i insert into a node, using either tinymce or fckeditor. i've tried different variations of installing and uninstalling the following modules: - image - image attach - image gallery - image import - image assist - image cache i know i'm probably missing something simple. i have two drupal installations and they both have this problem. thanks for your help.
