Read-only image field
If the image field is read-only, then all the Paste and Scan options will be absent or greyed out and there'll be a marker saying R/O at the bottom of the Cardbox screen. If this happens to you unexpectedly, the likeliest cause is:
- You are using a database that was originally created by an older version of Cardbox.
The cure is straightforward: use the command Tools > Management > Rebuild > Database to rebuild the database.
Why does this happen?
Cardbox 3.0 stores images in a different way from earlier versions of Cardbox. If you are using a database that was created by an earlier version, Cardbox 3.0 tries to keep the database compatible with that version, and this means that it can't store images. Once you have rebuilt the database, it becomes a genuine Cardbox 3.0 database (unreadable by earlier versions) and so Cardbox 3.0 will be able to store images in it.
Other possible causes
Of course, there are two other possible reasons for the image field to be read-only:
- When you designed the current format, you have marked the image field as being read-only.
- The user profile you are currently using is only giving you read-only access to the image field.
We mention these possibilities last because they are less puzzling and people ask us about them less often.
