Thank you for responding to my question.
I didn't add the = sign. The system added it automatically after I inserted the field name with brackets before and after the name. That makes me question if there's still something I'm doing incorrectly as it pertains to the control source.
I blocked out the full path because I'm a little nervous about broadcasting the entire path which leads to the server. It goes something like this:
\\servername\foldername\foldername\foldername\ .... etc., until it gets to the actual image file.
I know I can store the images on the local drive, but again, I feel in the long run it's prudent to plan now to prevent database bloat later on. Additionally, this database will be stored locally, as well as on the server where it will be viewed by another person. That's another reason why I feel it's important to have the images linked to the server files as opposed to being embedded on my desktop. I'm working on the premise that if the images are embedded in the database on my computer and my computer crashes, the copy of the database on the server will end up with the images being deleted? Is that correct?
And lastly, I can take care of inserting the suffix -- thanks, I didn't know that was necessary.
