GetImageSize

Description

array getimagesize(string filename);

The GetImageSize() function will determine the size of any GIF, JPG or PNG image file and return the dimensions along with the file type and a height/width text string to be used inside a normal HTML IMG tag.

Returns an array with 4 elements. Index 0 contains the width of the image in pixels. Index 1 contains the height. Index 2 a flag indicating the type of the image. 1 = GIF, 2 = JPG, 3 = PNG. Index 3 is a text string with the correct "height=xxx width=xxx" string that can be used directly in an IMG tag.

Example 1. GetImageSize <?php $size = GetImageSize("img/flag.jpg"); ?> <IMG SRC="img/flag.jpg" <?php echo $size[3]; ?>>

NOTE: This function does not require the GD image library.
