Photo Workbook Question

[High Desert]

I have been using the workbook to better understand AP.  So far so good, until I got to the "Discovery" chapter and was working to resize the astronaut and element photos to fit into the background (page 428).  For the life of me, I cannot find where you resize the image.  I see resizing for documents, but not images.  Where do I find this?  Thanks and I feel pretty dumb right about now ):

Hi High Desert,

Welcome to Affinity Forums

Select the Move Tool, click on the image you want to resize then drag the corner handles over the bounding box. By default Affinity Photo will resize them keeping their proportions intact unless you press ⇧ (shift). It also does this for other objects/layers which possess an intrinsic aspect ratio - like text -.

This behaviour can be changed in Affinity Photo Preferences, Tools section Move Tool Aspect Constrain dropdown.

Thanks for the help.  After trying, unsuccessfully, many times to do this, resizing would still not work - until I figured out that I had to uncheck the layer for the astronaut.  Once done, the box and handles showed up and all went well from there.  Cheers - happy New Year!
