How to use ddblock to create slideshow? I am having problem creating slideshow with DDBlock

Created a new block 'DDBlock1' from 'admin/structure/ddblock'
    Cannot configure Block: Selected "Input Type" as "Content Type" but under "Content Type" drop down box, only option is "None" (as shown)



I am stuck here - how do I direct DDBlock to pick images from an Image field in a content type I have??
Have you noticed that the help text says


  Only content types enabled in the settings tab of the ddblock module will show up here


?

As far as I can tell from your question, you haven't enabled your content type, and thus that's likely your problem.
