Show image size on image picker

[david-crespo]

I'm always wondering about the image size when I look at these. It would be very easy to include. Related to #1777, could fix together.

Little active state glitch coming through there too – family name and version number should use the accent colour.

Is this about what we want for the disk size piece of it?

[david-crespo]

That would do it for me, though seeing it makes me wonder how we should round. I think the mock images are exact GiB multiples, but obviously that’s not true in general. I’m thinking at least one decimal point, maybe two?

One decimal point should definitely be sufficient.
