Re alignment issue.
We have been trying to reproduce this here with all combinations of widgets, post formats and images http://testing.hydeinternet.com/. But all seems fine on this site.
Firstly post formats and images posts will always offset differently since an icon is only 48px wide. As in the tests above.Though it looks like you are just using small feature images rather than the post format option.
So I have tried small icon feature images in test above, which also work fine.
Could you try this in your custom css:
.los-custom-post.clear{width:100%;}
Remove afterwards though since if it works I’ll add it elsewhere. And leaving it in custom css would break the widgets in other contexts.
