It would be much more efficient for File & Image Uploader (http://z-o-o-m.eu/).
I am not sure if there are enough users/devs interested but many YetiShare owners go easy way with this app.
Without chunked upload the API is quite useless for uploading because usually the servers do not allow large files to be uploaded as a single chunk.
I remember inquiring about this years ago. I had to give up and write my own private file hosting script to handle chunked uploads in API since most of uploads exceed 100MB. You better learn to code than wait for it. Try picking up a framework like laravel or symfony instead. It took yetishare years before they even had a decent code overhaul (v5?) but kept having security risks that aren't gonna happen if you're using laravel/symfony since they have basic security against those exploits.
