I have a picture of many people but want to highlight one person. I thought that I might be able to use an arrow pointing at that person, but how do you make an arrow? Where do you get it from? How do you put it in the picture?
Or perhaps you have another way to highlight that person?
I will have a caption at the bottom of the picture saying who it is but it may not be obvious where that person is and an arrow, or something similar, would be much easier than writing a description of where that person is.
If it is an advantage, I could put the picture on ImageF1.
