I once built a shop like this for a client. Just place an image in a folder. Put the price in the file name. Then they wanted more features... each article needs to have an article number, fine add that to the filename too. Different categories, easy just use folders... I thought it was an elegant solution. Then they wanted more functions, and I added more variables to the file name. They eventually switched to full fledged e-commerce software.
