Load image link first in Editor, then show image when focused

Small thing that could be good for the next live coding session — in an app that has lots of images, it takes a while to get the Editor loaded and because it wants to show a nice little thumbnail for each row — this is great, but impacts loading time when first accessing the builder.

I think it would make sense to show the URL first, then when you click the cell, it should load the image as a preview (instead of loading them all at once).

Perhaps an on/off toggle switch? Make everyone happy?
