There are two ways you can add photos to a contact or a job using the JobNimbus 2 mobile app. You can add photos from your phone after taking them, or you can take photos from within the mobile app.

The size and amount of photos affect how fast they transfer to the web app. A strong Wifi connection should speed up this process. If you take large amounts of photos and your connection is mobile data only it may take longer for the photos to sync to the contact/job in the web app.
If the photos still have not synced to the Web app after a few hours of strong Wifi connection (this may happen with large batches of high-resolution photos), try adding one photo to another contact (could be a test contact) this may help restart the photo sync.
Don't delete the app during a photo sync or you may lose your photos, especially if you took them from the app and are not uploading them from a phone gallery.
