Can't find any images

Some quick comments:

Good use of REST activity and XPath activity. I would set Retries to 2 on the REST activities to deal with network errors, in particular for the second service which is called many times.

Not sure why there is a merge with a single value inside the nested workflow, probably due to Taverna bug T2-495.

Inside Taverna, under "Details", No "Example" value given on the workflow input port - I would prefer the example mentioned here, "schuy" to be listed together with a description. Similarly no workflow metadata has been provided under "Details" for the whole workflow.

 

I'm not sure if this workflow is meant to work with the examples given - as for "schuy" I get 10 URLs like <font>http://www.fly-ted.org/1478/thumbnails/2/medium.jpg - but all of them give 404 if I try to retrieve them in a browser.</font>

 

I added a new REST activity with the (non-escaped!) URL parameter {url} at the end to try to fetch the images so they can be viewed within Taverna - however I get similar 404s here. 

For the other two suggested example inputs Adh, or Act5C I get significantly more data back on the output anyNames - but on flytedImages I get either empty lists (the XML has no thumbnail element) or error documents. The errors seems to be caused by an Internal Server error on terms with spaces - so that's not a fault with the workflow.

And so I am not able to get any images using this workflow, I am a bit confused..! :-)
