Click the "Let's GO!" window to open the dropdown menu of webcams sectioned by region and sorted alphabetically by volcano.
Use the right and left arrow buttons to go back to the previous image or advance to the next. Press the Start/Stop button to play the slideshow automatically.
Drag the bottom right corner of the grey box that contains the image to resize it to your liking. Note that images will fit and keep their proportions, but smaller images will not be enlarged beyond their original size. Also this works best when using a mouse. It can be done on a touchscreen but the "handle" is small and a tad fiddly.
NOTE that some source's cameras may not display in the viewer on this site due to third-party-content limitations. You will likely get better results if you download the HTML file from my Downloads page and open it directly in your browser (as opposed to via localhost).
