Two things determining how big a picture file is, one is the number of colors that a picture will show. A file type that only handles only 256 colors (like the .gif format) is smaller than a file that can store 16 million colors (like the .jpg format). The other thing is compression. This is essentially how the pixels are coded into the image. Different compression rates can yield different image file sizes. This is because the mode of compression will treat details in certain ways.
JPEG = Joint Photographic Expert Group
Jpegs are the most used standard on the web because they do double-duty. They keep image size relatively small AND they preserve a lot of colors, 16 million.
That being said, JPEGs do have some drawbacks. Even though JPEGs can treat a lot of color, they're what's called "lossy" That means that to save space on disk, JPEG compression loses some of the contrast. Such loss is more notable depending on the picture, but one of the most tell-tell signs is slight wash-out, with color richness turning slightly pale.
As a side-effect of its compression format, changing a JPEG image size can have adverse effects, yielding "artifacts", spots where the compression quality has been significantly diminished. So while transferring an original image to a JPEG is a good option, it becomes less good the more converting, compressing and resizing you do.
BOTTOM LINE: JPEGs are the preferred meld of image quality and space conservation. Some loss of finer image details (washout). Use for normal photos when size on disk is an issue. For most web-based entities (programs, user-interfaces, logos, web-components) use space-friendly PNGs.

Google+ is making a big splash, but it’s still too early to determine if this is, in fact, a big fish or just a big belly flop. Google already has one social network to its credit, the rather tarnished Google Buzz, but with Google + the largest search engine in the world has upped the ante a bit and turned out what appears to be rather impressive. Not perfect, of course, but then – is anything?
Google+ Basics
Anyone on Facebook is familiar with the basics of social network. You gather up your friends and update each other on the comings and goings of your days, your deeper thoughts and the important milestones in your life. You share pictures, status updates and location changes. Google+ takes all of these same ideas and updates them using a circular concept.
When you first join Google +, you’ll be invited to complete a new profile and to add your friends. Since Google+ is still in a beta or trial version, this can all change over time as Google tweaks and changes the program to be even more user friendly.

Facebook has become even simpler to use. You can now download the Facebook Toolbar to show on your browser while you surf and work online. The Facebook Toolbar lets you know which of your friends are online and sends alerts regarding how many messages and other notifications you receive. You can also update your status directly from the toolbar and reply to messages quickly and easily making your Facebook use more in line with your other activities.
