Thanks for your answer! Sorry, I wasn't clear about my question. I already know how to show the images by uploading them to Images and media files menu option, but I noticed that if I upload the images there, they are not actually included in the template (only in my own project), which means everyone who wants to use this template should also do the same process again.
So my question is do we have a way to include them in the SAM template so others can directly use the template without worrying about the images? Hope it makes sense and thanks again for your help in advance.
