add thumbnails to bookmarks widget

[Lake_Worth_BeachAdmin]

I have a bookmarks widget with 2 bookmarks from my web map.

how can I edit the default thumbnail for these?

It appears you can according to this help doc but the layout does not resemble the same procedure.

Joe,

  Currently there is no way to set the thumbnail of a web maps bookmark.

only booksmarks that are created in the widget itself?
