Would it be possible to add in the ability to input negative numbers easily? EDIT: And I'm having issues setting my external sd card as the temp file path. I'm using a Sprint SGS3 (SPH-L710) running 4.4.2 and I tried "/storage/extSdCard" and "/mnt/extSdCard" and both are giving me "ERROR: Invalid path name" any solutions?

Is there some post limit I'm not reaching? Or is there a guide somewhere on how to do this? EDIT: Nevermind, figured out that if using a photo from Dropbox, it has to be in the public folder, and the file size can't be over 200kb.
