You can upload arbitrary data into the namestorage of your name. So open your Qora client: In order to use the namestorage you need to register a name, if you don't have a name yet you can register one here (names must be lowercase!) http://127.0.0.1:9090/registername . After that browse to http://127.0.0.1:9090/index/namestorage.html . Choose your name from the dropdown menu. After that choose a key under which you will find the file later (e.g. myfile.txt). Use the browse button and choose your file and press upload. After that is done you need to press the submit button to upload it into blockchain and approve the security call. Keep in mind that there is a 50 transaction per batch restriction at the moment, so if your file exceeds that limit uploading it will be forbidden, so 139KB might be too much if it can't be compressed well.
Keep in mind that the namestorage is public so after uploading the file everyone will be able to download that file here http://127.0.0.1:9090/yourname/yourkey so you need to encrypt it yourself if you don't want others to read the content.
