Php Resize Image To Max Width And Height. A positive x value will take you to the right of the image and a positive y value will take you further down. The getimagesize function will determine the size of any supported given 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 and the correspondent http content type.
When using these functions it is important to remember that php considers the top left corner of an image resource as its origin. We will be henceforth using php to decrease the image dimension and render it so that a smaller size is only downloaded on the client end and not the original image. If you set both to 100 the image will be stretched.
If the background size property is set to contain the background image will scale and try to fit the content area.
