masterarbor,
Animation only impresses the site owner, not the viewers. Flash is also the enemy of a site owner. Fancy stuff serves only to impress the owner. Surfers are looking for information and don't want to be distracted or bogged down with fancy stuff while searching. Animation is usually a larger file size too which adds to the download time. With male surfers, you have roughly 10 seconds to get their attention. With woman, 1/2 that. LOL! So you better keep to the simple and offer your message in a clear and precise manner. Many people are still on dialup and considerations should be made for that.
============================
Green Options,
You like many others pass on the misnomer that the picture's physical size has to relate to the file size. They are two different things. Case in point; look below: The first pic is your picture and the next one I modified.
Picture above is 23kb in size.(approx)
While picture above is slightly under 9kb in size.
And, if you look at the picture below, it's only 80% the size, yet it's file size is 34.4kb... the smallest, yet largest file size.
Load times are minuscule in comparison, but if your site was graphic intensive, the larger file size pics would bog down the loading time for sure. Like I said, it's not that big a deal. I've seen much worse. LOL! Since these pictures are not that large in file size to begin with, noticeable differences will be hard to determine to the unknowing eye.
