Would you mind using MineSkin API? As I know it has accounts to getting texture and signature data. It can be easy to get skin data with url, not sure btw.

looking forward to it

Do you only want to download skins from MineSkin or also upload files to to it?

As for me, I would only like to download.

But I've already made data base of skins (SQLite3) #99 (comment)

On the other hand, someone may need to download skins.

My reason for this suggestion was upload, so yes, upload would be nice. Because we need accounts to upload. I have one spare account at the moment which I could use for this, but there are people who have none. As MineSkin has lots of accounts and available API, it would easier.

Implementing it shouldn't be hard, probably you know that but I'll tell in any case. You have to send HTML POST request with URL. In return, it will give texture and signature data as JSON. So, you only need to address this data to your already functioning methods, I suppose.

Any updated on this?
