Hi Leo,

There is no setting to achieve this. You would have to template override some theme files to prevent the tooltip from showing. Below are some of them.

JoomlaFolder/components/com_easysocial/themes/wireframe/stream/photos.php
JoomlaFolder/modules/mod_easysocial_photos/tmpl/default.php
JoomlaFolder/components/com_easysocial/themes/wireframe/helpers/widget/albums.php
JoomlaFolder/components/com_easysocial/themes/wireframe/photos/popup/item.php
