image_size has no effect when parameter columns=1 is set.

Trying to change the image size to thumbnail but stays full width of column.

[grid content="post" number="16" columns="1" show_date="true" show_author="true" image_size="thumbnail" show_content="true" content_limit="30" show_more_link="true"]

Right now there is CSS making the image width 100%. This will probably have to change in order to allow more layout options with the grid. I can remove that CSS too. The only issue is that without that CSS on some browser widths the image won't fill the full column, which is ugly.

@christiebizbudding your code above will still cause this issue, but you can fix by doing image_align="center". It's a bit "quirky" but I think allows things to remain flexible.
