Here is what @Philio told me yesterday:

Wanted to get your thoughts on loading the album images. The thumbnail URL that's returned by pwg.categories.getList is very small and of unacceptable quality for a high resolution (~500 ppi) flagship Android phone. I see that I could use the representative_picture_id to then call pwg.images.getInfo and get a better image URL (also gives the ability to make a device specific selection) and finally download the image. Slightly concerned that this might end up in quite a few HTTP requests and could be a bit slow in certain network conditions. Is there a simpler way that I could perhaps do this that I've missed?

So, pwg.categories.getList returns the "thumb" size in output field "tn_url". On such screens, it would certainly be better to use the XS or S size.

@modus75 and @mistic100 what do you think of adding an input parameter thumbnail_size (same possible values as pwg.getMissingDerivatives::types (but only a single values) ie square,thumb,2small, xsmall, small,medium,large,xlarge,xxlarge

Thanks @plegall I'll keep an eye out for updates. I've implemented it by iterating the list for now and I would think it would make sense to keep this in for better compatibility with older versions, once 2.8 is released. I think it's worth the extra requests personally, here is "thumb" vs "large" on a Nexus 6P (2560x1440 xxxdpi) for comparison:

screenshot_20160203-003407

Once you've added this feature if you have a 2.8 test gallery on a public URL that you're able to share with me that would also be handy!
