I'm sorry to hear about your upload experience. Can you please say if the image goes up at all? If it is that when you try uploading you get a band with an error message, please check to see if your image is the correct size, and if the JPG format is saved at the correct compression, quality 10 or 12 - max. Otherwise you might be having issues with your Internet service. If you are having intermittent Internet service you will also have that error message; also if you have ping above 60. You may use a speedtest application to check the speed of your internet service.
I hope you found this helpful. If there's anything further we can help you with please let us know.
