Why can I only unlock some elements in my master template in Adobe InDesign?
So I am using templates, and can override the locked master items (e.g. text boxes and headers) yet cannot seem to unlock an image (which I am using as a placeholder to replace with the correct image every time I use the template.)
On most items on the page, I unlock by pressing cmd + shift and clicking on the the dotted outline of whatever it is; but for some reason I cannot get to the image.
Why can't I unlock / alter the image element on my master page, and what can I do to make it possible?
Definitely sounds to me like the image placeholder is locked in the master page itself.
Double click on the relevant master page and select
Object/ Unlock all on spread
from the top menu.
