Facebook is the most widely used social media website. Upload and share an image on Facebook is quite easy and literally, anyone with basic computer knowledge could do it.
But you may get some errors due to privacy and other settings.
The most common error is the Attachment Unavailable Error. Although there are several reasons for this error, you could try one of these four methods to fix it.
First Option: Change Public Sharing Setting
Log into Facebook
Click on the three dots
Pick your story from News Feed
On the right-hand corner click on the drop-down menu and select Public
Second Option: Upload to the specific group directly
The second is to upload directly to the specific group instead of sharing the link
Go to the Facebook group you want to post either by clicking on the left-hand side or through a search
Click on Add Photo/Video and upload directly (Also check whether the post is set to public)
Then Select Upload Photos/Videos and upload
Third Option: Modify Security Settings
The third option is to modify your security settings of the image before posting it.
Right-click the image on the computer
In the bottom select security
Check on Unblock and click ok.
Fourth Option: Set Privacy Setting to Public
On the top-right of the Facebook homepage, click on the arrow in the menu bar
Select Settings and go to Privacy
Under Your Activity – Who can see your future posts, click on Edit
Set the setting to Public
