Comment 3 for bug 262739

If the map was the only place the small version was going to be used, it wouldn't really matter if you did it on the fly, because the map shows only one person's picture at a time, so a little bit of wait for the image then wouldn't matter much.

However, a team's gallery page <https://edge.launchpad.net/~bugsquad/+mugshots> probably should use a small version too, to make the page faster and more compact for large teams. In that case, the small images should be pre-generated, otherwise that page would be extremely slow.

So, I suggest generating the small version (ideally with Lanczos resampling) whenever the large version is changed.
