I am going to prepare presentation slides for a research presentation. Below I am showing an example of type of images people generally include in such presentations. The presentation has been prepared in Latex which I know to use. But, the image includes many discrete components, e.g., faces, arrows, and text, stitched together.
I am not sure which graphic software is best suitable for creation of such a graphic. To clarify, I am not planning to create individual “components”. Those I will use ready-made, downloaded from Internet. The problem lies in compiling those together to create a meaningful image as per my needs. Will Gimp be sufficient, or are there easier alternatives?
