I have an old mxd that uses several hundred custom made picture marker symbols. We don't know where the image files that were inserted as pictures marker symbols are, or what format they were in. We're trying to search our files to find said images but Arcmap (10.3) doesn't provide that information anywhere we can find. Inserted pictures give you the path, but not so with picture marker symbols for some reason.
Is there any way to tell the file name and/or format of these inserted picture marker symbols?
