Is returning with Media upload failed
Please advise what could be the problem. We are trying to test few products from a partner site.
Try downloading the image and uploading it, do you get the same error?
I'm not the OP but I have having the same problem. In my case, I can load the image from my local machine after download, but it will not load from the URL. I prefer the URL because ultimately I will need to load several hundred images. I originally encountered the problem on the bulk import, which lead me to try it in the product UI and I get the same result with both methods. Any guidance or direction is appreciated.
