Hi,Welcome to AEM Community !!On Dynamic Media Classic Desktop app, when
you submit a Full Publish job, you get a Catalog manifest file.That file
has the list of all the assets on your DM Classic account and it has a
section name "Resolution", if that show the dimension of your images,
that should work for you. As Diksha mentioned, please contact our
support via creating a ticket on Admin Console
(https://adminconsole.adobe.com) and configure your FTP Server for
manifest delivery. Thanks,Vikram ...
