Trying to upload an image as a cover to a Portfolio, but keep getting "Error Code 400" ...

Good Evening all,

I keep trying to upload an image, from my MacBook Pro, as a cover to a new Portfolio (street & travel) on my site, but I keep getting this error (please see attached photo); and for the life of me I can't seem to find out what that means.

Any help would be appreciated.

Thank you,

Trying shortening the filename of the photo.  I downloaded an image off the web with a really long filename and this happened.  Shortening the filename of the .jpg worked for me.

Thanks @Chansterly, I was searching for that and found your reply - sorted! Thank you!

Thanks a lot ! I had an error but without any code and turns out it was just about renaming the file. Would be interesting to indicate it in the interface. 

Thank you for your reply, I got the same error.
