Welcome to TBN!
You get your unit from Nekoosa? Those guys were pretty cool to deal with, especially Bill.
Make sure the picture format is .jpg and within the file size requirements. I believe there is probably a size limit to the pictures you may upload, usually around 2-3 MB.
You could try clicking the "Basic Uploader" and see how that goes.
We'd all love to see your tractor!
