Gallery view is a special type of view which represents your records as large cards. In particular, gallery view highlights your attachments—images, documents, and more.
To create a new gallery view, click the dropdown arrow in the view bar, then click the "Gallery view" option from among the new view creation buttons at the bottom of the dialog.
The cover field is a designated attachment field, the contents of which appear at the top of each gallery card. When creating a gallery view, if your table has at least one attachment field, the first attachment field will be automatically set as your gallery view's cover field.
If you have multiple attachments in the cover field, you can mouse over the cover to scroll through the different attachments at a glance.
To change the cover field, click on the Customize cards option in the view bar. You can then use the dropdown in the cover field section to select a different attachment field as the cover field. You may also choose to have no cover field.
The slider at the top of the Customize cards menu allows you to choose whether the images on the cover fields will crop (fill the entire photo area by zooming and cropping the photo) or fit (zoom out to show the entire photo).
You can also choose which fields to show or hide on the gallery cards in the arrange fields menu by checking or unchecking the boxes for the appropriate fields, or by clicking the hide all and show all buttons. To rearrange the order of the fields as they appear on the card, simply click and drag the field names into the desired order using the drag handles to the right of the field names.
You can drag and drop a file (or multiple files at a time) onto the cover field of any gallery card to upload that file to the cover field. Note that you'll need to have the cover field already visible (toggled on) in the gallery view before you can drag and drop attachments to records in the view.
You can also create a new record by dragging and dropping a file onto the add new record button (the one which looks like a big + in a circle).
If you drag and drop multiple files onto the add new record button, you'll be asked whether you want to create multiple records out of each of the attachments, or if you want to make one record with multiple attachments.
