getimagesize

问题 Another image overlap issue here using Masonry and Ajax to append items in Wordpress. The first time more items are appended, the images overlap. However, when the page is reloaded, the images no longer overlap. I realize after doing some research this has to do with calculating the height of the images. From the help page on the Masonry website, it is suggested to use the getimagesize function in order to specify the width and height of the images. However, this is where I am stuck. Because

问题 Does anyone know all the possible results for the 3rd value returned from PHP's getimagesize() function? Example this code below will return: $imageinfo['2'] = 2; for a jpg image, $imageinfo['2'] = 3; for a png image, $imageinfo['2'] = 0; for a gif image.

问题 I have this situation where I have some pictures: http://www.example.com/test1.jpg http://www.example.com/test2.jpg http://www.example.com/test3.jpg .... some of them might be dead links and the image will not show up, but a small broken icon.

If the image is broken it errors out. And this is
