Hi Everybody,
You can now use medium (or small) thumbnails in your galleries.
Just edit the gallery, select "medium" as the "Thumbnail Size", and click the "Update Gallery" / "Update Gallery Details" button.
Want to update ALL of your galleries? You can quickly apply the change to your entire account by editing your root gallery, selecting medium as the thumbnail size, checking the box to "apply to all subgalleries", and clicking the Update Gallery Details button.
You may also need to decrease the "columns" value and "apply to all subgalleries" for that value as well.
We know that this does not fix issues with how pages look on phones and tablets. We are working on bigger changes that will drastically improve the way all pages look on all devices. This was just a small improvement that we wanted to offer in the meantime.
Enjoy!
