The higher the transparency, the easier it is to see through the picture. This allows you to put pictures over text, and still read the text through it.
GIF is such a format that supports animation and transparency. See the related question for more details on the GIF format and some other formats that support one of these features.
.jpg -common for most normal pictures .bmp -short for bitmap .png -similar to bitmap, allow transparency effects .gif -typically used for animated images, also allows transparency
commonly used formats are png and jpg.
PNG
Pictures and other images. These are the most common image formats, and can be used for anything from a desktop wallpaper to a graphic in a slideshow.
Black and white - no transparency.
PNG and GIFF
The most basic formats for images depend on the image itself. Images of documents use PDF formats, really images by a digital camera would be .jpg. Images that have animated motion are more .gif formatted. Those are the most common.
Generally, that would be a PNG image with a transparency declared. Not all browsers recognize transparency, but there are often workarounds that have the benefit of doing it at the sacrifice of speed.

You cannot convert an image to sound. It is because of the difference in the file formats of both.
A flattened image has only one layer. After the image is flattened, it has the same appearance it had before. The difference is that all of the image contents are in a single layer without transparency. If there are any areas which are transparent through all of the layers of the original image, the background color is visible. By flattening an image we introduce significant changes to the structure of the image. It is normally only necessary when you would like to save an image in a format which does not support levels or transparency (an alpha channel).
