By default PDFs and Web Links import on newsletters with a default cover image. You can replace it two ways:
Option 1, if your preferred cover image is already in your Content list:
Simply drag and drop your preferred cover from the content list to the default cover:
Option 2, if you haven't uploaded your preferred cover to the Content list:
Hover on the default cover, click ' Edit image' then ' Upload image' and select the image to upload.
The new image now shows underneath ' Select and crop ' so you can always upload more images, review them and edit/crop them if needed.
Once you're done just select your preferred cover cover and click ' Apply 'at the bottom.
