Hello,
To get a pinterest style layout use the
RokSprocket module by
RocketTheme.
After installing, create a new module of
RokSprocket type then in the module creation page select the
Mosaic layout, use
Easyblog as the
content provider and hit continue.
Apply this module to your blog page and voila but...
You might come across a problem where you are displaying both the blog posts and this new pinterest layout module so to sort this you may be after a "blank page" component.
I created one that works with Sh404sef which you can download on my github
here.
Once you install the Empage component, set your blog page to that and then the only thing that should show is the module.
Then to hide this module in the blog entry page look at this feed
here.
I hope this helps.
