How to converting RGBa (m x n x 4) .tif image to RGB (m x n x 3) .tif

After help on my previous question, I have found that some images I want to crop (using imcrop) have been converted to RGBa due to some previous operations in paint.net (I flattened the images but still can't remove the Alpha). I thought they might be cmyk and tried a conversion I found but this gave a weird reversed image so thus I am pretty sure I have RGBa.
Does anyone have any code to convert my images within my cropping function? I have spent hours searching but to no avail.
Many thanks

Why can't you just do
% Extract only channels 1, 2, & 3.
rgbImage = rgbImage(:,:,1:3);
??? What do you mean you "Flattened" the image? Can you attach your image so we can try stuff?
