Problems exporting images from photo

Are your photos in iCloud Photo Library? Do you need the internet to access your photos in iCloud, or are you trying to export to a remote location?

If the destination flder is the problem, use the work-around to export from Photos to a folder on your Desktop with "file > Export", and then move the photos from that folde rto the final destination folder.

Check the preferences in Photos (from the Photos menu). Is iCloud Photo Library enabled in the iCloud tab of the Photos preferences, like this?

In that case your original image files will be in iCloud.

Stop using iCloud Photo Library

Important: If you decide to turn off iCloud Photo Library, first be sure to select “Download Originals to this Mac” in the iCloud pane of Photos preferences, so all your original photos can be downloaded from iCloud to your Mac. Be sure to allow time for your originals to download before turning off iCloud Photo Library completely.

• Choose Photos > Preferences, then click iCloud.
• Deselect the iCloud Photo Library checkbox to turn it off.

After you turn off iCloud Photo Library, the Photos app on your Mac can’t access your iCloud library, and any edits you make to photos on your Mac won’t appear on your other devices. Your library remains in iCloud and available to other devices that use iCloud Photo Library. To turn off iCloud Photo Library on all your devices, open the iCloud pane of System Preferences, click the Manage button, then click Photo Library. Click “Disable and delete.” Your photos and videos will be deleted from iCloud Photo Library in 30 days, unless you click Undo Delete before that time.

I'm having the same issue - I have my Originals on my mac and in the Cloud and am attempting to share an album, it says internet connection required. I have a connection that works just fine (I'm posting this). So the only way I can share an album is to turn off my iCloud Photo Library across my devices? Doesn't seem to make much sense, heavy setting change to just share some photos, seems like more of a bug. If you have any suggestions please let me know. If it continues will turn it off and use another service outside Apple. Any help would be appreciated, thanks.

No, you can share photos using shared albums with iCloud Photo Library enabled.

it says internet connection required.

You may besting such an error if the internet is occasionally having drop-outs - some applications will have time-out errors, others not.

There may be also a firewall or antivirus software interfering. Are you using a firewall?

No firewall that would block Photos to my knowledge, no antivirus. I was able to share two videos, a couple others had the same need internet connection error. Disappointing, wish this would work more consistently. Haven't seen this before when sharing other albums.
