Re: [O] [Orgmode] Extending paste to auto-archive a copied image

Hi,

I wrote some code to fulfill the proposal you discussed two years ago, using 
xclip and perl to yank image file in link format for org, and save the file 
named after the image's timestamp.

Which means it's working for xwin clones, and I'm currently using Ubuntu 12.10.

The function is named "x-selection-value2", attached at the end of this mail. 
I'm binding it to C-v. 

The naming of the yanked file is kind of casual. Please feel free to change it.
