No. Yola is a no-code builder made for people who are not developers, which for most artists means the hardest part of the day is the photography, not the site. You pick a template, upload your images, type the titles and sizes, and publish. Nothing in it needs a line of code.
You can start for free and publish on the free plan. Moving to a paid plan costs $9.95/mo and gets you a custom domain, more pages and the full AI tools, with a free domain for the first year on annual billing. Current plans are on the pricing page.
It depends what you are selling. Prints and editions have a fixed figure, so publishing it removes a whole email exchange and lets someone decide on the spot. Originals are commonly listed as price on request, which is standard in the trade and keeps the conversation open. Commissions are always quoted, so explain what moves the number instead of naming one.
Camera level with the center of the piece, even light from both sides, plain background, and crop right to the edge of the work. The single biggest improvement for most artists is color accuracy: shoot something neutral in one frame and match to it, so what arrives in the post looks like what was on screen. A phone in good daylight beats a DSLR under a ceiling bulb.
Both can work at once. A marketplace brings traffic you would not find alone and takes a commission for it, and Instagram is where a lot of first contact happens. What neither gives you is one address you own, where the work sits in the order you chose and is not competing with ten thousand other artists. Galleries and curators also tend to ask for a site rather than a profile, because a profile tells them nothing about how you think about a series.
Keep it up and mark it sold. A sold piece is evidence that people buy your work, and it often prompts an inquiry about something similar. What you should not do is leave it sitting on your Available page, because an inquiry about a piece that went two years ago wastes a warm lead.
