Ahh, ok - thanks for sharing that, @Paul Kalousek. I understand better what you’re referring to! In Windows, the shortcut to temporarily suspend those red "Snap to objects" guides is S, which in Mac OS is achieved with Control.
Since you mentioned wanting to turn the red guides off entirely rather than holding a key down the whole time: good news, you can! Open the main Preferences menu, then toggle off Snap to objects. You can also get there faster through the quick actions menu (Ctrl + /) by typing "snap to objects." That'll fully disable the auto-alignment guides for your image-placement workflow, and you can flip it back on anytime the same way.
Let me know if that gets you the control you're looking for!
