Hi Mike, yeah it starts to get hard the bigger the mosaic gets and with this one I found it easy to add each panel to the mosaic as I acquired it. That meant just opening my PTGui project and selecting 'add image' then align and it did it right away. I wouldn't want to know what would happen if I had to do it from scratch each time haha !
There is an issue with Uploading Photos (attachjments). I am not sure what the problem is, and I am looking into it. You can still try to Create your Threads and Upload your Photos, but it is hanging up during the Upload.
