Getting rid of the BORDER around my image

Hi everyone,

I have seen that other people are having the same problem that I am but many of them are familiar with code that I just don’t understand.

So with tat said I am hoping that there is someone that can help me.

My website is https://www.consultantfreesred.com if you open the page you will see that the pictures that I have on there have these borders around them.

Can someone please help me get ride of these borders around my images ?

Thank you very much in advance for any assistance you can offer me
