GLAMorous - Zero values and inaccurate pageview data for many files

[Rhodo Dendrites]

Posted this a while ago on Commons. Realized I left it on the talk page of the gadget, rather than the tool itself. Ah well. I verified the same users are still happening.

Seems like a super useful tool, but for my purposes there's an issue that basically breaks it.

I looked for pageviews in June 2018 for files in Category:Files uploaded by Rhododendrites (all). For some images, it shows uses and pageviews. For others, it shows uses but 0 for pageviews. This includes recent and old images, including some that should have relatively high traffic. One example is https://commons.wikimedia.org/wiki/File:Chuck_Palahniuk_(21955).jpg . When I first noticed, I assumed it was because it was uploaded on the first of June, so maybe it was excluded for some reason. But this FP from last year https://commons.wikimedia.org/wiki/File:Juvenile_Nubian_ibex_in_Mitzpe_Ramon_(40409).jpg likewise shows 0 pageviews. I've also tried this with May 2018 instead of June, and had the same result (obviously the June upload had zero pageviews, but the older file likewise shows zero).

While I'm here, I'll also make a feature request: allow sorting all files in the dataset by number of uses or number of pageviews (the former is already possible elsewhere, but as far as I know there's no tool that orders a set of files by pageview).

Thanks
