Craig, what is the URL where your graphic is located? Mine is at
http://www.romineinc.com/BBQ/grafix/Bob-BQN.png . If I press the IMG button it will automatically insert the BBCode tag [img].%20And%20if%20I%20press%20the%20button%20a%20second%20time%20it%20will%20alternately%20insert%20the%20BBCode%20tag[/img]. Notice the slash mark " / " is the second example. The slash signifies the END of the command. You place [img]before%20your%20graphic's%20URL%20and[/img] directly after it. Make sure there are no spaces in the command. NOTE: You can type BBCode tags manually without clicking the buttons and they will work just as well, as long as you don't make any typo's. The following is and example of how it should look, but I will insert underscores " _ " so that it won't display the graphic and you can see the code.
