The above issue is now resolved and v1.0.2 of the application is now available for installation from the Marketplace.
Now that this is issue is resolved v1.1.0 will be worked on next and will have the following in it:
A little tweak in it to assist with the following situation:
First post in a topic has an image
Activity Stream is configured to "Show content items only"
Entry for the topic, which shows the last reply, doesn't display an image as the last reply doesn't contain an image
The tweak I am putting in will allow you to choose to show the image from the first post, or an image from the latest post to contain an image.
Issue mentioned can be 'avoided' by using the "Show content items, review and comments" setting instead as that displays an entry for each post from a topic.
The linked image used in the stream/search results will be he stored thumbnail of the image, and not the image itself (required a little trickery to figure this one out, as the thumbnail is not available by default)
Addition of some extra CSS selectors.
An issue reported via PM will be looked into:
