What does that mean? Do you mean you want to hide text in an image, like my attached program? Or do you want to watermark an image with an image of text (like my other attached demo)?

Simply average the two images, or paste it in, like my attached demo shows. Let me know if you need further help.

You'd have to specify the full path (folder plus base file name), unless it's on the search path, which you can see by typing path on the command line. For a specific file, you can find the folder it's in by using the fileparts() and which() functions:
>> folder = fileparts(which('peppers.png'))
folder =
'C:\Program Files\MATLAB\R2020a\examples\deeplearning_shared\data'

Matlab Folder is NOT only ‘Current Working Folder’.
Matlab search all paths that exist in MATLABPTH.
One can check with the Matlab command ‘path’ in the command window.
Matlab stores some images, videos and relevant data in its respective toolbox demo folders.
Like images ‘onion.png’ and ‘peppers.png’ in the below path (example). This path presents in MATLAB search path.
“Matlab Installation Folder\toolbox\images\imdemos”
Example: C:\Program Files\MATLAB\R2012a\toolbox\images\imdemos
