Website builder

I am a professional artist with tons of images in all media. I’ve had 3 previous companies design my website over the past 5 years. All fine, but none of them let me upload new images, update text or do anything myself, they all charged me an arm & a leg to do anything. I want to do it on my own, I even have all the images, text, designs, layouts all finished, but I’m not web-builder savvy, barely know HTML & though I’m trying to understand website language, I am just not grasping it all. I can’t seem to find a reputable builder on-line or otherwise that are FOR ARTISTS. There’s good web-builders on-line (I think they are) but not really for artists, I need something that I can have multiple pages with multiple pics that expand to show really good quality images. Anyone can recommend something, any personal experience? I’d really appreciate it. THANK YOU!
