Vivaldi web browser has built in blocking. Plus I added uBlock Origin by going to in the browser to Tools> Extensions> Chrome web store (in upper right).

Otherwise use uBlock Origin add-on as I do for Firefox which is what I use most of the time. Tools> Add-ons

I added the UD icon on my toolbar for easy access. Right click on toolbar> Customize Toolbar then drag the icon where you want.
Customize Firefox help: http://davidswebsite.com/Firefox_tabs/firefox_tabs.html
I also have it installed in Chrome. I hardly use it as it is slower and cannot be customize.

Using uBlock Origin you can right click on an image or ad and Block element.
