Is it possible to open the full size image in portfolio

Wanted to know if it’s possible to open full sized image in portfolio project if you click on it.
I add projects into my portfolio and display my artwork as a featured image. Then I needed to change the functions.php so it wouldn’t crop my images so much. Is it possible to change it so it will display the full image but in reduced size?
Code: add_theme_support( ‘post-thumbnails’ );
add_image_size( ‘shapely-full’, 1200, 830, true );
add_image_size( ‘shapely-featured’, 730, 630, true );
add_image_size( ‘shapely-grid’, 350, 300, true );

I hope you are doing well today.

That is actually the code used to edit the image sizes, you can make the changes there by editing the height and width values there.

Best Regards,
