Graph images flicker on gallery screen

Reseminata

From the gallery screen, go into a goal, and then back to the gallery screen.
Or, alternatively, pull to refresh your goals

Expectata

Only graphs that have changed should update

Resultata

Every single graph briefly flickers the placeholder bee image.

I have noticed this as well.

It happens because
a) all goals are fetched each time goal gallery is loaded (whether or not there have been any updates)
b) each request for a thumbnail uses the "cache buster" URL, each of which is unique. From the looks of it, the image thus is not cached locally by AlamofireImage.

I am working on a solution for this.

The screenshots in the google play store for the android Beeminder app show an option for setting the interval at which the app will check for updated graphs.
It not clear to me how up-to-date those images are.
Nonetheless, is such a setting along a direction in which this app should be headed?

Negative, the plan is to remove that setting from Beedroid. Anti-Settings Principle!
