Designing the multi-stimuli Experiment

[Dilip Kumar]

Dear David,

I am using the trial version of E-prime which contains Getting Started 
Guide and User Manual only, it does not include any tutorials. We are in 
the process of purchasing licensed version which will require some time. 
Meanwhile, I am trying to learn the experiment designing process and I am 
stuck in using images as stimuli.

Any directions on creating image stimulus list and using it would be quite 
helpful.

Thanks and Regards,
Dilip
