Fixation cross before each target

is there a way to upload the pictures all together and simply tell the system to show them one per time, with the related multiple question alternatives? - You can use loop and merge for this. Put all the image url in the field1 of loop & merge and in the question html img src just pipe in the field1

Thanks!

 I need to show a fixation cross for 500ms before each picture - For this too, you can add a fixation question at the end of the loop and merge block with timer question associated with it on same page, and auto advance set to 0.5 seconds

is there a way through JavaScript (and not loop&merge) to include a fixation cross before a graphic multiple question?
thanks!

You can use the below code:
jQuery("img").attr("src","FIXATION_IMAGE_URL");
setTimeout(function(){ jQuery("img").attr("src","ACTUAL_IMAGE_URL"); }, 500);
Are you at least using loop and merge to show 90 images, suggested in very first comment?
