Tumblr use best resolution

The script should look for the best version. If it's not available, it should look for the next best version. Thank you.

I am getting the same problems!
I guess they changed URL strings?

"It turns out that the raw images are being stored in "data.tumblr.com" now instead of "media.tumblr.com".

This doesn't work: http://media.tumblr.com/ce26e4910f94b459f4d16a6bc639d135/tumblr_ohfvftXRKT1r16th2o2_raw.png

But this does: http://data.tumblr.com/ce26e4910f94b459f4d16a6bc639d135/tumblr_ohfvftXRKT1r16th2o2_raw.png"

These links exist. The only problem is certificate issue.
