To add a cover, it’s very simple as you simply need to publish a photo containing evlaaCover in the filename.

1. Be careful with the capital letter, you must have evlaaCover in the file name
2. If the photo has already been published, you need tore publish her (right clic and mark to republish)
3. If multiple photos have evlaaCover in the filename. The last published will be used as a cover for your gallery.

⚠️ Warning, this cover photos will be uploaded with a (2000px long hedge) and without watermark to offer a clean user experience to your clients.
