On trunk if I try to upload a huge image to Commons, after selecting the file, I cannot insert it. All I can do is cancel.
If there is a limit to the file size, there should be a message to the user stating the file is too big and to select a different (smaller) file.
The same file works on
Sakai - 12.0 - QA2 10/16/2017 - Sakai 12.0-QA2 - Server ip-172-31-6-159
File is 3.71MB, 3456x2304
