Hi @Ramona_Russo - if the image you want to display is on your laptop, then you won’t be able to reference this in the page designer. It is expecting a URL to an image (by definition, somewhere out on the web). For example, if you have a company/organisation website, you can use your logo (by referencing the URL) in the page designer.
For example, here’s an Airtable logo from the web:
Copy this string into the Image URL box and you will see the image appear on the page designer.
You can’t upload an image to the page designer and even an attachment in a record will not work (However, an image URL from a record will work, but obviously, only for that record in PD).
You have to upload it to any image hosting site, like https://imgur.com/. Then copy the image URL and paste it on Airtable.
Even you can do it with Google Drive, making it public and copying the image URL (don’t use the URL generated by Google Drive, as it is a link to the ‘item’ on the drive and not the file itself.
You can make a table called assets and put the image there. Then you can click on the picture and in lightbox mode right mouse click and copy the image url… Airtable hosts a public version of all images attached to airtable.
