Issue Summary

Email-to-board doesn't add an attachment as a card cover anymore, and it was a useful feature. It used to work in previous versions.

Steps to Reproduce

1. Open a board,
2. Copy the email-to-board link,
3. Send an email to the email-to-board with 3 images attached,
4. The card will be created and the images will be attached, but the card doesn't have a card cover. Previously, the first image attached would become the card cover.

Expected Results

The first image attached in the email would become the card cover.

Actual Results

None. No card cover on the card created through email-to-board.

Workaround

You need to manually add one of the images as a card cover after creating the card through email.
