Match Thumbnail crop/fit settings to image crop/fit settings

[TetonCountyExtension]

I'm working on a story map detailing the various different local farmers and food producers in the area. I would like to use farmer logos for the thumbnails, so I selected the "fit" image to window setting so that the logos always show up looking nice, but in the thumbnails they are often cropped and looking a bit unprofessional.

I realize that currently, thumbnails always crop, but I would prefer that when I chose to fit an image, the thumbnail also does the same, even if that means having a smaller/tiny version of the logo because it would give a more professional look without me having to go and download copies & add whitespace to all the 50+ logos so that they appear correctly. 

Thanks for you consideration!
