It seems that whatever image I point to in position 4 is also shown in position 6, no matter what position 6 is actually set to. Please see http://studentsoftraders.com for an example.
And, by the way, my IP address was blocked by my host, because they thought I was slamming them with a DOS attack! The circumstances were that I was trying to get the six panels looking right, and when I would reload the page, I would see the six panels' Alt Text for a very long time (minutes) before the images would finally appear again. The support tech said he thought the images must have been requested over and over again, until the firewall finally blocked my IP address. (This just happened after I upgraded to Studio Theme 1.0.3, which may or may not be related to the problem.)
