help--alternating text and image stimuli

[Rick O'Gorman]

You're welcome, glad to contribute something back.

I made a typo in my previous post--toward the end of the long paragraph, 
it should read "So in my relevant list, I had a variable called STIMTYPE 
that took either a value of 'pic' or 'text' depending on another 
variable setting".

Sorry about that,

Rick
