The textual description of the image is important for a number of reasons. If images are turned off in a browser then the textual description is displayed instead. If the image is not found then the textual description is displayed. The textual description may be displayed whilst the browser is still loading the image. The textual description may be used in browsers for the disabled.
The alignment is relative to the baseline of the text surrounding the image. Top aligns the top of the image with the top of the line of text, whilst bottom aligns the bottom of the image with the bottom of the line. Middle centers the image on the baseline of the text. Left aligns the image with the left margin and right aligns the image with the right margin.
Images are scalable and specifying a value different from the original dimensions of the image will cause the image to be scaled. There are certain advantages to specifying the dimensions of the image even if they match the original. For example, a browser may continue to format the page whilst an image is loading if it knows the dimensions of the image in advance. If images have been turned off in a browser then because the dimensions of the image are known, a box of the correct size can be displayed in place of the image. This leaves the formatting of the page unchanged.
Setting the border to zero causes no border to be drawn, whilst setting the border to be one causes the thinnest possible border to be drawn.
