Photos are managed per workspace (meeting room, day pass, private office). The venue-level gallery is also editable from the venue page.
Updating workspace photos
Go to Resources & Rooms, open the workspace, and use the photo editor to upload, replace, or remove images. You can set a main image that's shown as the workspace thumbnail.
Review before publishing
Photo changes go through the same review step as other listing edits — they'll appear on onecoworking.com once approved.
Tips
Use bright, wide-angle shots of the actual space
Avoid stock photos or logos
Make sure the main image matches the workspace type (a meeting room shouldn't have a day pass photo as its main image)
