We keep getting this error, how can we fix it?

We want to create an application using a flower file and whenever we run it, it shows this error. I am not sure why this occurs since I did put a colored image. I even checked the size per instructions, yet I don't understand how they can be related. Please help me solve this issue. Also, how can i put the file into the workspace?

I am not aware of a strcmps() function. Try strcmpi or contains

and try

[rows, columns, numberOfColorChannels] = size(im1)
if numberOfColorChannels == 3
    % Convert to grayscale ONLY if the image is color.
    i1 = rgb2gray(im1);
else
    i1 = im1;
end
