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:
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.
That seems to have fixed it. Should I leave until it is incorporated? I also noticed that the Feature image is then scaled to 87×87 and seems to fill that void between text & image. Would it make more sense, therefore, if I rescale my Feature image to 87×87?
Update: I tried sizing the image to 87×87 and there was still misalignment and as I do not want to loose real estate, I have reverted to the 47×47 images. I like this size and your fix seems to work, though I would prefer if the post had the ability to scale as though the image were dealt with as an icon. Thanks again for your ongoing support and let me know whether I should leave the code in the custom or when/if it is incorporated.
