You can use `imagesize` to get the size without displaying the image. === imagesize(path) » [width, height] === Quickly grab the width and height of an image. The image won't be loaded into the cache or displayed. The `width` and `height` of an image object will return its pixel size as well, but you'll need to check it before you resize it. >From the manual: === height() » a number === The vertical screen size of the element in pixels. In the case of images, this is not the full size of the image. This is the height of the element as it is shown right now. If you have a 150x150 pixel image and you set the width to 50 pixels, this method will return 50. Also see the [[width]] method for an example and some other comments. _why
