Next, we took a nine-question quiz regarding pictures.  You can read the quiz along with the answers and my notes by clicking HERE.  (If you want to download and save the quiz with answers, RIGHT-click instead and choose "Save Target As..."

After the break, we took another quiz.  You can read the quiz along with the answers and my notes by clicking HERE.  (If you want to download and save the quiz with answers, RIGHT-click instead and choose "Save Target As...")

In going over this second quiz, I showed how to make sure you see all file extensions and I said I'd create a "How To" page going over each step in the process.  You can access the How To by clicking HERE.

Speaking of our How To tutorials, I showed you the How To page and explained how to open the folders to reveal the drop-down menu.  However, I decided to redo the entire page so you no longer have to click on the folder to see what's there.  Why not take a minute and check out the new How To page?  http://www.4kcc.com/techmain.html

I also said that I would give you definitions for each of the most common picture file types.  Here they are:

.bmp	Files ending with this extension are picture files saved in the bitmap format. These files are usually larger in size than most of the other picture formats.
.gif	GIF, Graphics Interchange Format, is a file format for storing graphical images up to 256 colors.
.jpg	Files ending in .jpg or .jpeg are graphic files named after the Joint Photographic Experts Group who created the standard.  Jpegs use lossy compression for photos. The degree of compression can be adjusted, allowing a selectable tradeoff between storage size and image quality.
.png	Portable Network Graphics (PNG) is a bitmapped image format that employs lossless data compression.
.tif, .tiff	These two file extensions both represent the Tagged Image File Format which is used to store photo images and line art.  Scans and faxes are often done in this format.

 

I also want to correct something I said.  "PDF stands for Portable Document Format because you can embed fonts and styles which will appear correctly on someone's computer, even if their computer doesn't actually have the font or style installed.  PDF files are protected, though, if a password is used.  As I mentioned, the format is often used for legal papers which could be changed if written in a word processing software program.

The seminar was divided into 2 videos and both will take some time to load and play, even on high speed.  If you're looking for Joyce's "I'm Addicted To The Web" performance, it's around the 23 minute mark of the 2nd video.
