Photos and Links

I may know about wine, but html is a total mystery to me. With the help of my computer scientist son-in-law, I think I have finally figured out how to do links and photos. Hopefully there will be a photo with this post and there are a few links in the sidebar. We are headed to Yakima this weekend with Bob & Kathy and hope to come back with some good ideas and photos. Does anyone know how to edit photos in blogger? How to size photos, etc.?
