xxx: people, how to add a text to the picture?

YYY: In any graphic editor.

zzz: you can dim and make a presentation slide, any texts and characters are inserted into the slide

www: and you can upload the image in Excel, format cells in the appropriate size, insert text, color cells in the desired color, make a print screen, insert in photoshop, cut, save as jpg, archive in rar and send by email... but why?
