Will Changes I Make To An Image In The Image Editor Affect Other Places The Image Is Used?

I've read the guide it says to right click another place it says double click neither works in dominknow. At the bottom of the screen I see Accessibility tab with Alt Text and a fill in but can't find a way to made the grayed out Edit Asset button work.

Hi,  I'm using the scenario builder and have a few questions.  1. Is it possible to add images into each speach bubble? I can see the option for audio, but not for an image.  2. Is it possible to format the text, i.e. if I want to bold or italicising something?  3. Is it possible to add in links to pop ups or hyper links into the speach bubbles?  4. Is there any way I can use the images in the scenario as their own stand alone images? I can't seem to find a full body avatar in the stock media...

is there a way to input a full width image? so you open your program in a web browser it goes full width?  

"Is it possible to create a tooltip for an image or a hotspot?"  

I have text which appears on screen by typing. Is there anyway to get the images to appear after this animation is completed. I cannot see any options to do this in Triggers or Actions without having to time it myself.   

Is it possible to add additional icons to the library? If not, what are the dimensions of the icons so I can add it as an image?   Thanks
