imgurup-3ds Imgur upload client for 3ds
I spent my last few days writing an Imgur upload client for 3ds. It's very basic at the moment,nothing special.Upload Images upto 5 mb to imgur. If everything work correctly then it would give you the link,otherwise an error would be displayed on the screen.
Implement a file explorer. Preview the images before uploading.
Press B to open the explorer. Select a photo. PROFIT !
