If you want to add labels to a figure, what's wrong with text() or annotation()?

If you want to add text directly to an image, see insertText(). If you don't have CVT, see the comment here and the answers it links to.

I'm not really sure what "attach" means to you. Do you

1. want to display the value of the variable above the image. The image is on an "axes" and the "axes" is on a "figure" and you could have some caption/label above the image?
2. want to "burn" some text that has the variable name and value into the pixels of the image? Like with insertText of the Computer Vision Toolbox?
3. want to put the name and/or value of the variable into some EXIF or IPTC metadata tag of the image file? Like with exif_tool?
4. want to "hide" the variable in the image like with steganography?

Or something different than those options?
