PS : Oh and don’t forget to bevel your cube with a Bevel Modifier !
If your image is bigger than 250 pixels in width or height, you may notice that the particle grid can’t go higher. In this case, I’d suggest sclicing your image sequence and using multiple planes. Or, you can use a single plane and add edge loops until you have as many vertices as you have pixels and emit particles from vertices but there is some additional setup afterwards and I think the first method is more optimized in terms of memory, not to mention that you can decrease the resolution temporarily to have a decent viewport framerate.
