The up and down arrows will increase or decrease the amount of time each slide stays on the screen. If you have a slow internet connection, longer times are necessary to allow time for the images to download.
If you are unable to fit the entire image on the screen, hitting F11 (in Firefox and Internet Explorer) will change the display to full screen. Pressing F11 a second time will revert the display back to normal mode. To gain additional compression click on the gallery image and the display will compress further.
If you prefer to view only one category of images, click on the "Galleries" menu and select one. Your slideshow will then be limited to those in that category.
