Mt Whitney Zone Forums Picture Gallery snow trips

Hello, I am a new member trying to learn the image loading process. Thought I'd add a few ski trip photos since I am hoping to get in another ski tour before things melt out. I'm keen to ski around the upper Kern area on my next trip. Thanks for any advice on adding images, Harlen.
Question: How can I change the caption on a photo, and still keep the image in the same place?
