PageSpeed recommends: Specify image dimensions

Hello,

I tested my page on gtmetrix.com and one of their very obvious (and simple) fixes recommended is to specify image sizes. I will do it for images I provide on that page but can I ask you to do it on your images? That will be beneficial for all your users. Thank you very much in advance.

Best regards
Jan
