1 year, 3 months ago: @scottprock I took the Shortstack webinar this morning and they indicated that the custom app image (that shows next to Photos and Likes) size is 111px x 74px – I couldn’t quite tell if that is on this list because it might be called something else.
And I think it’s been verified that the new width for custom apps is 810px.
But great info! So many times I’ve just guessed at sizes, so this will come in handy.
