i wrote it for users, who can't pay for your official paid addon, for example, for me
I think, you're a person who is much more rich than me. I know standard programming rate for such kind of work is from $10 (3rd world countries) up to $80/hour. How much time have you spent on the developing? I doubt you spent less than 3 hours programming/studying it. Programming storage addon, I've spent about 30 hours in total, plus the time for testing/fixing the errors; programming file attachments/galleries addon, I've spent more than 60 hours in total, and the development still continues.
So, for example, if you spent about, let's say, 8 hours for your rough work, you gave away $10*8 = $80. Woudn't be 3'times less expensive to buy a ready, stable, proved and nice solution instead? I'm sure you can pay, as everybody else, for such kind of solutions, if you analyze your time, but you do not want to pay.
I would say this is an addon for the for users, who don't want to pay for our official paid addon. Accordingly, they don't want to get any kind of quality support, they don't want possible errors fixed immediately.
Ok, I found the link to the files, but... I don't want to register to upload any file and see how it works. I want to stay anonymous and just try to upload some file. Is this possible?
