I indeed have tried picWorkflow, am currently using it, and it does what it claims - which at the baseline allows you to upload and distribute to multiple agency sites. This does save me time and effort, especially as my connection is not super-fast and I would rather minimize my time dealing with files uploads. It is a worthy effort, and I support it!
You can read an interesting article I conducted with Bob Davies, the creator by following this link:
http://www.stockvideoseller.com/public_html/interviews-2/bob-davies-picworkflow-and-.html At the moment it has some minor drawbacks. Financial reporting is promised to appear at some point, which would be helpful. Social network promoting is also promised to become online at some point - and this too would be great. I was a active user of the iSyndica social network promotion tool, which let you upload to Facebook and Youtube. The iSyndica tool was seriously flawed, as it did not let you brand the clips with link back information. This meant all the clips of your which go viral (and several did) bring you little if any results sales-wise.
The PicWorkflow process does not let you keep a filename you have given your files, but renames them to avoid confusion in the server. This creates some minor additional work as you need to identify and rename them at each of the targets they are distributed too - or a least figure out what they are again. Metadata, that is the description, keywords, are not transferred to the target sites yet - although they are saved along with the jpeg you need to create for your clip in the upload process and may allow this in the future (but most likely not to all the sites). Unlike iSyndica, the site does not archive your clips once they get the online, but rather uses a pays as you go system each time you perform an activity. Back when I was using iSyndica, I found the cost of storing and using the system to be around 7 - 10 US cents per clip. The cost seems significantly higher than iSyndica as you must purchase storage for any clips you want to remain online and also you pay by the size of the clip you are working with on picWorkflow.
I do find myself being more cautious in my use of the service, primarily on it's costs, but this may be due to my increasing knowledge about which sites are non-performers, and which sites will reject what.
