Quote - I just finish a rendering for the challenge and post it... **

Question**: Is the .brx file required for upload?

It won't upload the artwork without the original file. I just tried to upload a br6 file and it politely told me that it was either not the correct file type or it's over the weight limit. but it nevertheless uploaded the jpg files. So now I'll have to wait for it to be approved before it appears on the page. LOL

 I just uploaded the pic again where it asked for a file and it worked.
