The7 supports 8 blog post formats (fig. 1.):
Each of them has a bit different layout on a blog page:
Standard (featured image links to a single post page)
Image (looks very much like the standard post but has different rollover and click on a featured image will open bigger image in a lightbox).
Video (click on featured image opens video in a lightbox)
Video post format previews. There are two kinds of video post preview: image and image with “play” icon. You can choose preview appearance in the “Post options” box, “For video post format” option.

Quote (text-box with an “author name”)
Link (short text description with an external link)
Gallery (displays a gallery instead of a featured image)
Gallery post format previews. First of all, it is necessary to add a standard WP media gallery at the beginning of the post using standard WYSIWYG editor.
Second, there are three kinds of gallery post preview appearance available in the “Post options” box, “For gallery post format” option: standard image gallery, featured image with gallery hover, slideshow (see fig. 2-7). Note that slideshow preview allows to set proportion for slideshow images.
Status (looks identical to “aside” post format).
