Larger verisions of many pictures are available by clicking on them. If the picture opens in the same window as you are reading from, use the "Back" button to return to where you were.
When you view the larger version of a picture, it may be much larger than the screen, requiring you to use the scrollbars a lot. There is a remedy:
The picture will fit within the screen if you have Internet Explorer set to "Enable Automatic Image Resizing". (In browser window use Tools > Internet Options > Advanced). Then, if you DO want to make the picture full size, click on the expansion icon that appears when the cursor is over the image.
(Older versions of IE may not have this remedy.)
Some items may open in a new, separate page, which may not be full-size. To make the page full-size, click the Maximize button (the button with a box next to the "X" button in the upper right corner). Click the Minimize ("-") button to get it out of the way, or the "X" to close it up.
You can make the text larger or smaller via "View"... "Text Size".
You can save a page you are viewing on your computer, including the pictures, by selecting, in the upper left corner, "File", then "Save as..." with "Web Page, complete" in the "Save as type" box. ("WebPage, HTML only" saves just the text")
