I have been using Squarespace for about 6 months, with some good sales, but not too many. I have three questions, with attached screen shots numbered to match the questions. 1. I'd like to improve my Home page to get people interested in clicking through. Any suggestions? 2. I'd like to know how to organize my drawings and paintings better so people don't give up scrolling through to get to something they really like. There are a lot of items ATM, over 100, and it takes a long time to scroll, especially on a phone. 3. How do I allow people to get a large image for closer inspection when they click, or maybe scroll-over to magnify the image? Thank you so much!!
