I made a cross platform desktop app for people who upload their photos and videos to microstock agencies called Xpiks (https://xpiksapp.com). Initially I was selling one-off forever licenses but last year started moving them to subscription. So far progress is steady and I keep working on it. The app is made in C++/Qt and I’m looking for people who might be interested to join. - Source: Hacker News / over 2 years ago

You can use Xpiks to do that, both uploading from your own computer or from "Xpiks Cloud" (you upload once and we upload to many). I'm a microstock contributor myself and Xpiks was created specifically for other microstock contributors (it's not just an FTP uploader). Source: over 2 years ago

I'm sorry you read that. Xpiks is a microstock contributor's workhorse: both metadata and upload. Check out yourself: https://xpiksapp.com/ (you can see tutorials section to get a grasp of the features). Source: almost 3 years ago

StockSubmitter - advanced submit functionality. Source: about 2 years ago

Use ImStocker, Xpiks, or StockSubmitter instead. No 15% sales cut, and no 3 month wait time as you are uploading directly to the marketplaces with these tools. ImStocker is the best value, Xpiks has the best design, and StockSubmitter has the best submission automation. Source: about 2 years ago

Xpiks is my favorite. StockSubmitter is really good too. Xpiks has more of a modern design and is easier to use. StockSumitter is great because not only does it help you upload to many different marketplaces, it also automates the final submission process on the individual websites. Source: about 2 years ago

My favorite is Xpiks. This is an affiliate link but I'm not shilling, I've tried all of the multi-upload tools. StockSubmitter is good too, its design is dated but its powerful because it uploads AND finalizes submissions on the marketplaces. Source: about 2 years ago
