How do I set a source image inside directory with .ImageSource?

I'm using Matlab App Designer ver. R2025b and I’m having a trouble assigning correct path for my image. Path is “\Assets\_1\rect.png”.

app.I_first.ImageSource="\Assets\_1\rect.png";

I also tried using imread() function to no effect.

img=imread("\Assets\_1\rect.png");
app.I_first.ImageSource=img;

The problem is that it's unable to find this file using this path. Also I’m attaching error messages that gives me while using imread() function.

Error using imread>get_full_filename (line 635)
Unable to find file "\Assets\_1\rect.png".

Error in imread (line 395)
        fullname = get_full_filename(filename);
                   ^^^^^^^^^^^^^^^^^^^^^^^^^^^^
Error in main/DD_FirstValueChanged (line 337)
                    img=imread("\Assets\_1\rect.png");
                        ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

baseFolder = fileparts(mfilename("fullpath"));
imgPath = fullfile(baseFolder, "Assets\_2\", "rect.png");
img=imread(imgPath);
app.I_first.ImageSource=img;

This is the solution

[Stephen23]

fullfile(baseFolder, "Assets", "_2", "rect.png");
