SH Open worldveiw AndreasT layers are a good choice, top right there's a camera, click, pick your shot, download will open into a new tab to copy into gimp or imageJ, alternatively copy the tab address and paste that into 'insert image' second icon second row [mona lisa], click it and img /img appears, but both in brackets, check with preveiw. Another alternative, on worldveiw, is to click the chain/links, copy the shortened link and paste that using 'insert image', if you want to switch between layers click the icon [eyeball] on the left of layers/base layers, that should get you started.
