: Arranging images, arrows, text and similar for research presentation I am going to prepare presentation slides for a research presentation. Below I am showing an example of type of images people

I would suggest one of the following:


TikZ is a LaTeX package that enables you to draw diagrams directly from LaTeX source code. The main advantage is that the text is rendered by LaTeX and you can typset formulas as in LaTeX. Thus you do not have to hassle with other ways to render formulas and your text matches your main text in font and size. The main disadvantages are that it has a slow learning curve and is not WYSIWYG. Due to the latter, I would not recommend it to draw something like your faces, should you have the need one day (but you can still import those with TikZ).
Inkscape is a free vector graphics program. It allows you to embed other graphics and is thus suitable for such jobs as connecting two existing images with arrows. It has tools like a formula renderer and allows exporting images in a way that allows for the text to be rendered by TeX. It is WYSIWYG and thus more suitable for drawing something like your faces. It’s SVG- and thus XML-based and thus you can directly work with the files on a source basis and reasonably version it. Finally, you can embed other images as links, if you want to. On the downside, it also has a slow learning curve and it does not as nicely integrate into TeX as TikZ (not that it integrates badly).


I recommend against using any pixel-based software like GIMP, as the result does not optimally scale, which is particularly visible on low resolutions, which projectors tend to have. In particular text and thin lines suffer when rescaled.
