UPDATE: found the “wgpoi:attachmenttemplate” option in the control, but it doesn't seem to work. If it's in the current database, does the “databaseName” still need to be entered? Tried, but no good. Couldn't find any documentation here, in the zip file or on github.
Also, just wondering if anyone still uses this, or monitors this project. If not, I'll look for another solution.
