How do you get the sideways carot to show / hide the images of the macros that you post up to the forum?

Click on the "cogwheel", top-right corner of the "post editing" box, and select "Hide Details":

[details="Summary"]
This text will be hidden
[/details]

...gives you:

Summary

This text will be hidden
