Because some members use slow connections, the forum software allows you to opt out of viewing pictures. You can change this setting on your preferences page.
Click on the "My Forums" link located in the upper-right portion of most forum pages.
Click on the "My Preferences" link located in the list of links that run horizontally across the window.
At the bottom of the General Preferences section, you will find 4 check boxes. The third one governs whether or not you will see pictures in the body of posts.
While you are on you preferences page, check to see if you want to make any other changes.
After completing changes, scroll to the bottom of the page and click on the Submit Changes button.
