Require ruby and the oauth gem

How : use

• Fetch an api key on : http://www.tumblr.com/oauth/apps
• Add them to the script and enter your credentials
• then in terminal :

gem install oauth

if it fails (ex : on osx, with the default ruby) :

sudo gem install oauth

then :

cd /path/to/where/you/wanna/save/images
ruby tumblrLikeBackup.rb

I apologize in advance because I'm new to scripting...I've installed oauth, created my directories, got an API key (I THINK I did that correctly). But, where exactly do I store the actual tumblrLikeBackup.rb script? Locally? On my machine? I know, it's a dumb question, I'm sorry. I did try running it locally, in the same directory as I've set the image path to, and it fails with a message of "400 Bad Request (OAuth::Unauthorized)"

Sorry, i'm just seeing your message now (idunno why i don't have mail reminder set up for gist).

Yeah, you save the script locally.
Are you sure you changed the infos line 7 to 11 with yours ?

Yes. Same error for me. Wasn't sure what to put for "Default callback URL" tho
