Most of the images on my website are getting blocked unless Adblocker is disabled for the site.

My question is simple: what do I do about it, short of putting a message on the homepage advising people to disable it?
I've had potential clients email me asking for examples of my work, which is precisely what the website is for.
Don't get me wrong, I love being able to block ads when I'm surfing, just don't like it thinking my artwork is ads.
Do I need to get in touch with my web host about this?
Thanks, Sue
