I would like to present a slider scale with images at the time.
Is it possible to anchor a new image (ontop of each other, so it looks like a morphing image) to each increment anchor on the slider? I would like it so that if the participant is hover over 1 on the slider that an picture1 is shown on the same screen, and then hovering over 40 on the slider will show picture40 etc...
This is my current coding but I have not worked out how to anchor images to the slider. Also I am unsure whether the LIKERT function may be better to achieve the effect I am after. Any advice would be much appreciated!!!<text instruction1>

Rate the average emotion by using your mouse on a scale on the following page.
