Collection thumbnails

[HelenCooper]

Hi, 

Are there any recommendations or guidance for the image width / height / resolution for the thumbnails used in a Collection?

I had a look but couldn't find anything, and I'm struggling to get them looking good!

Thanks, 

Helen

Hi @HelenCooper! -- Sorry you're having issues getting your collection thumbnails like you want them. Could you share more information and maybe a screenshot to help us understand what isn't working about what you're currently doing? What look are you going for with your thumbnails? Which collection layout are you using?

Hi @OwenGeo , thanks for replying! 

I'm using the grid layout, and my images seem to end up looking fuzzy.    I played around with the ones here https://storymaps.arcgis.com/collections/d862a503b68643ce89ba586729ebe3b2 for some time before they worked ok, and now I have the issue with another collection (that's not yet shared publicly, but there's a screen shot below).  I just wondered if there was any guidance on the best ratios to use as I think they're not quite square? 

Many thanks, 

Helen

In grid layout the thumbnails are about 225x170px, which is about a 1.32 aspect ratio.
