Option to skip upload?

[mlnl221]

I would like to just take screenshots, upload them to imghosting and create an output description instead of uploading to a site.

Is that possible with the current args?

Usecase:
Now that onlyimage is dead, all my descriptions are broken images, i would to reup these images to imgbox or ptscreens but dont want to hash and upload the whole file just create the descriptions to update the links.
