I'm new to Evernote and trying to organize my crafting supplies into categories and add images as well. I can add the pictures just fine, however, I want a thumbnail to show up in the folder column, so I don't have to click on each one seperately to view the picture. A few are showing up but most are not. Anyone know how I can accomplish this on each and every note? I wondered if it may be due to the size of the pictures I add, but I am not sure how to make them smaller. Thanks for any help!
