Hello I have a difficulty of changing the photo size in projects. I want the tiles to be the same size, hope you can help me. website: www.mbklussenbedrijf.nl
Please try to use images of the same size in pixels or at least of the same aspect ratio. You can try to edit images directly in your WordPress Media Library. There even should be an option to restore original image.
Please feel free to ask any other questions that you might have.
Kind Regards, Roman.
