When I upload an image, if it has the same file name as one that is currently in the repository, it should overwrite the existing file. Instead, the repository will allow the new file to be uploaded with the SAME name as the other image file. That's not very good file management rules. At the very least, the newly uploaded file should be appended with -- filename plus a sequential number (ie. Filename-01.jpg, then Filename-02.jpg)
This has been resolved and is available in 5.15.4386.5544.
Thank you, Thuc, for your idea. We will share it with the Development Team.
