While viewing topics in the ZBrush Forum, you'll notice this new icon above each post...
Click this icon to view the topic in 'Gallery' view: images are represented by thumbnails for easy browsing. If you clicked from a post which contained images, the corresponding thumbnails are marked with this icon for easy reference.
Note: thumbnails are generated only for images uploaded to ZBrushCentral. If you post a message with an image that's hosted elsewhere, it's represented by a 'thumbnail missing' icon. If you wish, you can replace the image with an uploaded one so its thumbnail will appear in Gallery view.
Thumbnails may also be missing for other reasons; for example, the image tag may be typed incorrectly.
For certain topics (such as challenges): Gallery views display only images marked with [Gallery Entry] tags by default. At the bottom of the Gallery page you'll find a link to view thumbnails for all images, including WIPs. If you'd like to start such a topic, simply include a [Gallery Entry] tag in the first post.
We hope you enjoy this new feature.
