You can add text to an image using the the Edit>Copy to Image Info command in the text editor. You can retrieve the text, which is saved in the TIFF header, by pressing the "i" key (Image>Show Info). Macros can add text to an image by calling setMetadata("Info", string) and retrieve it using getMetadata("Info"). Plugins can add text to an image using imp.setProperty("Info", String) and retrieve it using text=(String)imp.getProperty("Info").
