我正在加载 jpg 的图片，但如果用户将 png 文件或 jpeg 文件上传为个人资料图片，该怎么办？有一个 jpg 的文件。
相同名称示例：abc@mail.com_profileimage.ext
我通过网址直接链接获取此图片。
<img style="width: 100%" src="http://proconstruct.co.in/upload_images/<?php echo $email.'_profileimage.jpg';?>" onerror="this.src = 'http://proconstruct.co.in/images/noimage.jpg'; ">
如果我使用$images = glob($dirname . "*");上面的给定前缀，我怎样才能获得最后保存的图像
