"I guess this can be solved in a two-step with a prototype with low res images and then an after delay with the hi-fi images so you can make sure there is loose spot whilst also giving the opportunity for the visitor to see the image in the highest possible quality."

"Another cool thing to do there is to change the background of the prototype to match the one you use, so there is not a black line in the side of your portfolio."

Ah yes great insight there! Thank you to mention that.

Would you mind if I add your insight to the writings so others can read it too?
