所以我正在开发以下图像上传脚本，基于现有的开源脚本。目前可在此处实时查看：http: //images.oneightynyc.com/
现在，如果您拍摄任何一系列常规尺寸的图像（小于 5mb）并继续上传它们，上传过程就很好了。上传文件，然后将您带到显示这些文件的链接代码的页面。但是，假设您上传了一些大图像，如下所示：
http://imaging.nikon.com/lineup/dslr/d90/img/sample/pic_005b.jpg
http://imaging.nikon.com/lineup/dslr/d90/img/sample/pic_003b.jpg
上传是在这个过程中发生的，但是脚本永远不会把你带到上传的页面。我知道上传实际上已经发生的唯一方法是，如果我浏览到图库页面并看到那里列出了文件。
这是处理上传的 uploader.php 文件：
