load delay for images

[duindain]

hey jarvis,
in one of my experiments i have a sequence of 40images all loaded and displayed in the same trial like so
1 15 1 0 1 pic1, 0,0,0, 40, pic2, 0,0,0, 40, pic3, 0,0,0, 40, pic4, 0,0,0, 40 etc.
You showed me how to display these correctly in topic

I have since changed the 40millisecond time field to this
rt:95,(889)>-9
this allows the 'movie' to be interrupted and goes straight to the rate emotion trial

anyway my question is the load times for loading the 40images are quite random between 2-8 seconds i realise this is because the program is trying to dynamically load 40images within the read ahead time set by the minmax settings i believe?
unfortunatly to make the 'movie' display correctly i have the minmax set to 0-40!ms
of course this is insufficent time to load the images is there a way to help in this situation a long load time is fine so long as it is a consistant load time in each case
there are about 40 of these image movies in the experiment

I was thinking adding a blank text file to the beginning of each 'movie' trial with 1000ms delay might help? this would give the images time to be read in hopefully.
