Mike, if you were to go to a page with many images (like a photo gallery) you will see thumbnails. A thumbnail allows you to "preview" an image an gives you the option to expand it by making it larger.
Also Trumpy, if you are using the Windows XP operating system, you can view the image related files types (jpg,bmp,gif,png) that are in you folders on your hard drive as thumbnails. To do this open Windows Explorer, highlight a folder that contains images, click the "FILE" drop down menu of the explorer window and ckick "THUMBNAILS". From then on the contents of that folder will appear as small thumbnail images of the actual image inside.
Guys, I was just curious as to the meaning of the term. I was reading a PDF file recently from the local Electrical Safety Service and noticed a small panel with "Thumbnails" written on it. I couldn't click on it, so this made me even more curious!. Paul, Sorry about inviting that sort of thing into your computer, I've never been to one of them sites, so I had no idea that they used them too.
From this main page, choose one of the subtopic pages - as they have the thumbnail links. Click on a thumbnail to view full size image.
As to the .PDF thumbnails, they are kind of similar, but instead you jump to a page in that document. Most of the time, when creating a .PDF document, the default settings make a thumbnail frame active - or your reader may be setup to make a thumbnail frame by default. Unless the document maker has setup thumbnails, there will be nothing in that pane. When there are thumbnails, they work just like Hyperlinks. Problem is they are like less than 10% of the document's size, so jumping to a page may be more of a "Crap Shoot" than expected! (meaning just what can be seen on the thumbnail!)
