It would be helpful to have a few more details on this issue. What has changed since you were able to successfully import photos without references? Are the files all of the same type?
On OS X 10.6.8, I created a new file, and imported pictures from a folder on the desktop. They imported without error. I closed the File and moved the pictures folder. When the file was reopened, the PDF file type wasn't in the container field. JPEGs, TIFFs and PNG files still were saved in the container field. The thumbnails remained in the proper fields regardless of the location of the original files.
Any additional information you can provide will be helpful in defining this issue.
As far as I can recollect, nothing has changed. I don't recall when I upgraded to the latest level of Filemaker Pro--that is the only possible change I can think of.
I would have upgraded fairly soon after it became available. The original database was created around June-July, and the latest records were probably added in September-October.
The files I am trying to import are from exactly the same source as the records that are already in the data base. They are all single page pdfs--Both the original images in the database as well as the ones I added a while ago that are now missing.
Interesting that all file types seemed to work OK except pdfs!
Thank you for your help!!
