From the release notes, major highlights:

'Fixed issue in the Journal that made image thumbnails not clickable'

Sorry, but I don't think that got fixed.. I just installed a fresh test copy of dnn7, added a Journal module, posted a picture and.. it's not clickable..

This is really frustrating.. I've been asking around and waiting for months and there are still no answers/fixes..

I can't advertize dnn's social features like this to my clients.. the first thing they're going to ask me is 'Why can't I click on the picture (thumbnail) I just posted?', 'Why can't you make pics bigger?' There's really no point to post 200px thumbnails that can't be enlarged..
