Edit Tif

[KrisOlsson]

Why can't I edit this tif attribute table? I want to add a field:

by chance is there a join involved?  You can't edit the join table.  You will have to remove the join, edit that table and rejoin

 I ended up exporting it into a gdb and now I can edit it. But that is a good point, because the reason I wanted to add a field was to have a field from the join table be added to that tif's table.  thanks!
