How to add multiple images to a step
Clarify supports multiple images in each step. When adding multiple images to a step the images become part of a single canvas that you can draw on and resize. When the document is exported, the entire canvas will be exported as a single image.
Adding a new screenshot
Click the "Add image" button
You will be able to capture an image just as you normally would in Clarify.
The image will be added below the current image. The image selector tool will be activated and you can then reposition the image and/or add a drop shadow.
Here is an example of the previous step after repositioning the images and adding drop shadows.
Adding images on the clipboard or from files
Right-click in step image area
In the contextual menu for a step image you will find the Add Image Using menu option. If an image is on the clipboard then you can select Clipboard Image. You also have the option to take a new screencapture or insert an existing Image File...
I think the arrow in the first image points to the wrong button. The circular arrow (bottom right) inserts a *replacement* for the current image. By trail and error I see the '+' button (bottom left) is the one that adds extra image(s).
Now I've found it, this is a useful feature I can see myself using. Thanks.
