As said you can upload multiple things however I do agree with you on DA not populating all metadate of an image. If you look at sites like 500px and flickr as example, everything is populated, title and keywords included. This is something which very much needs to be done and I have been asking for it for years now. It's like having a conversation with a kitchen sink however.
As you've already been told, you can upload multiple things through Sta.sh.
As for actually submitting multiple things at once, I don't like that idea anyway, and I don't think it should be implemented. Your watchers won't appreciate it, your groups won't appreciate it... Quality over quantity!
You'll be happy to hear that you can upload multiple files at once, using Sta.sh. This FAQ explains how to upload via Sta.sh FAQ #441:How do I upload to my Sta.sh? and this tutorial shows how to use Sta.sh step-by-step.
You will still have to enter the details for each deviation individually once you've uploaded everything, but there's really no reason to be submitting over 100 deviations at any one time, so as long as you're a bit more selective about what you upload, it's a more convenient way to submit
Haaha, no that was an over exageration xO But uhm, Oh yeah, ok i'll check that out thank you, i just didn't know how to get the St.ash actually to upload.
And i'm sure alot of us think so too.
So why not let us upload more than 1 picture at a time. Also it will save time for us and you.
