Hi I met a problem when I use alfresco generate thumbnails. I use the php curl send the post request to the <a>http://localhost:8080/alfresco/service/api/node/workspace/SpacesStore/66f766c0-4245-42e3-9133-06b9623f26e7/content/thumbnails</a>. And got the response with the follow message:

The reason is that thumbnails are generated asynchronously and the thumbnail rendition must first be requested. The way to do that is to append "?c=queue" to your URL.

If you want to make sure that you always get a placeholder thumbnail back when an actual thumbnail doesn't exist, append "&ph=true" to your URL.

So the full URL in your case to (1) request a thumbnail generation and (2) get the placeholder back until the thumbnail exists would be:
http://localhost:8080/alfresco/service/api/node/workspace/SpacesStore/66f766c0-4245-42e3-9133-06b9623f26e7/content/thumbnails/webpreview?c=queue&ph=true

Hi Jeff
Thanks for your replay. I used the URL you provided and still got a 404 error. But I use this url <a href="http://localhost:8080/alfresco/service/api/node/workspace/SpacesStore/66f766c0-4245-42e3-9133-06b9623f26e7/content/thumbnails/medium?c=queue&ph=true">http://localhost:8080/alfresco/service/api/node/workspace/SpacesStore/66f766c0-4245-42e3-9133-06b9623f26e7/content/thumbnails/medium?c=queue&ph=true</a> can receive an orange picture(not true thumbnail). I need to generate a thumbnail for a picture. So which thumbnail name to be used?
Thanks again.
Andy
