Default Image is being deleted.

I've tried several things to stop this from happening. I have the "Delete File" behavior on both my "Delete" page and my "Update" page. This works very well, but I just realized that if the default image is assigned to a record during Insert, and then later updated or deleted, not only are the images deleted as desired, but so is my default image. Not sure why I was thinking it wouldn't do that.

My attempts to correct this have been to put the default image in a sub folder since the Delete File behavior asks for the deletable folder. It still deletes the file.
I also tried adding the full path to that field thinking maybe it would write a new version to the upload folder each time it uses the default image, but it just simply inserted the path into the column of the table, which then didn't work because my php code includes a path before the binding of the image placeholder.

I'm sure that this is a simple fix, and I am just over thinking it. Any help would be appreciated.

Thanks,
