Note: The collage feature is not available on mobile devices at this time, and you are not able to create an image collage by editing a post that is already on the board. A collage can only be created from the Add a Post page.
You can upload up to 4 images from your own device and transform them into a collage for your post. To do so:
1. While logged in and viewing the board, click + Add to Board.
2. Click Add an Image, and then drag and drop your files, or click browse.
3. Now, select up to 4 images you'd like to upload from your own device as a part of your collage. You can always click Add more images if you only selected one photo to start.
4. Ensure you toggle to Collage, at the top of the page:
You may rearrange the photos within your collage by clicking and holding the crossing arrows in the top-left corner of each photo and dragging the image to its new position.
Zoom in/out on your images by sliding the dial across the straight line.
Choose a new layout for your collage by selecting different Layout options.
5. Once your images are aligned the way you'd like, click Add to post add the text portion of your post, and click Post.
Here's an example of a collage in its final form:
