Sets or retrieves the height of the object.

specifies or receives one of the following values.|
|height||Integer that specifies the height of the object, in pixels.|
|percentage||Integer, followed by a percent sign (%). The value is a percentage of the height of the parent object.|
The property is read/write
for all objects except the following, for which it is read-only:
The property has no default value.
Expressions can be used in place of the preceding value(s), as of Microsoft® Internet Explorer 5. For more information, see About Dynamic Properties.
If the height property of an img is specified, but the width property is not specified, the resulting width of the img is sized proportionally according to the specified height property and the actual width (in pixels) of the image in the source file.
Consider the following:
|Dimensions of image in source file (pixels):||100 X 50 (W X H)|
|Specified image height:||2in|
|Specified image width:||not specified|
|Resulting image height:||2in|
|Resulting image width:||4in ((100 / 50) * 2 inches)|
If you specify the height property of an img, and the height and width of the image in the source file are identical, the width of the image matches the height.
If you specify the height property and the width property of an img, the resulting image dimensions matches those specified.
Percentage values are based on the height of the parent object.
When scripting the height property, use either the pixelHeight or posHeight property to numerically manipulate the height value.
If dynamic changes are intended for the height and width, the original values should be set through style (e.g. "style=''height:200px; width:200px'') rather than through the height and width attributes.
This property specifies the calculated height of the object, in pixels. For table rows and table cells, this property has a range of 0 to 32750 pixels.
If you set the value of the corresponding HTML attribute using a percentage, this property specifies the height, in pixels, represented by that percentage.
The scripting property is read/write for the img object, but read-only for other objects.
