此处一次支持上传2个图片,上传后生成原图和质量较差的图,原图用于保存质量高的图片,质量差的图用于网页显示。

有些问题需要说明下:
jpeg图像生成的图像的质量的是一个范围从0(最低质量,忧心忡忡是什么意思最小的文件大小)到100(最高质量,最大文件大小)。而imagepng生成图像的质量范围从0到9的,传入的这个范围以外的参数则该函数不会工作。
判断上传文件的类型,$type = $_files[‘work1’][‘type’];。
创建各种格式的图片可以使用这些函数:imagecreatefromjpeg()、imagecreatefrompng()、imagecreatefromgif()。
