Just tried the new image uploader...very quick and easy.
Great, that's what i was aiming for.
One question about using pixlr's imm.io: The FAQ on the site refers to Remove and Rename tabs, but they don't appear to be available when auto-uploading screenshots via SC. Is there a way to delete the photos on this site once they've been uploaded by SC?
Afraid not. Using Imm.IO (at least through SC) means you don't have to provide any username or password or key, and you don't have to sign up at their site, BUT the consequence of this is that once a file is uploaded, it's out of your control.
HOWEVER,
If you download the latest Screenshot Captor beta you will now see you have an additional choice of upload service; in addition to Imm.IO, you can now use
ImageShack. With ImageShack you can provide a username+password, or cookie (your registration #), and optionally your own api key (not needed, will fall back to default one if not provided). IF you choose to specify those values associated with your ImageShack account, you can manage your screenshots there after you upload. And I must say it's worth the effort because it's a nice interface and you can delete anything you upload by mistake.
Let me know if you have any trouble with the ImageShack uploader module. One tip to look out for is that ImageShack seems to fallback on anonymous upload if there is something it doesn't like about your credentials. So after you put in your username+pass (or better cookie), make sure it really is uploading into your ImageShack account, and not anonymously. The LOG tab can also help here (look for <uploader> info).
I'm anxious to hear how you guys like the new uploader. It's been something I've wanted to add for a long time. I think for the next NANY event I'll make the uploader a standalone utility and make it easy to add (plugin) support for tons of uploading services.
TIP: when you sign up at ImageShack they send you an email that tells you your registration COOKIE; its the #s here "
