Adds an image's opening and closing tags to the tag stack, optionally providing a [code]width[/code] and [code]height[/code] to resize the image.
Adds an image's opening and closing tags to the tag stack, optionally providing a [code]width[/code] and [code]height[/code] to resize the image and a [code]color[/code] to tint the image.
If [code]width[/code] or [code]height[/code] is set to 0, the image size will be adjusted in order to keep the original aspect ratio.
