Hi Kimberley, I've been using Plogger for 5 years (happily with few problems). I've never come across being able to get Technical Support on the phone. Maybe you could describe a bit more in reply to this post.
Have you got any photos in your gallery, or are you a new starter? What version are your running? Do you see any error messages? Describe step by step how you are attempting to upload.
I am not very technical so may not be much help. But other users might if you share some more detail.
I have a simular problem. Been having it since 2011 and still no fix. I have about 10.000 images in my plogger db but for some reason plogger says I have no collections or albums so I can't add anything. Any tips?
