热门编辑： 我想到了。一切都很好，唯一的问题是代码告诉图像去的上传文件夹是错误的。我所要做的就是在目标文件夹上的“照片”之前插入一个斜杠。它在我的本地机器上工作的原因一定是由于自动添加了斜线或者某些东西......无论如何，一旦我修复它，它就像一个魅力 - 无论我使用什么样的.jpg图像：）
您知道吗，如果您遇到uploadify问题 - 使用调试功能：'debug'：true， - 这就是我能够看到它试图将文件放在错误的文件夹中的方式 - 我我不知道如何解决这个问题。
原始问题： 我有一个PHP上传系统工作，我可以允许用户上传图像或多个图像到网站。然后网站接收它们，创建缩略图，然后将它们和拇指存储在一个文件夹中。
它适用于一些jpeg图像，但是有一些jpeg图像（它们都是转换为jpeg的原始文件是相关的）不起作用。
有没有人听说过这个 - 莫名其妙。最大上传大小，一切都很好。这是一个奇怪的问题。
谢谢！
编辑： 这是代码。我现在已经改变了我的系统以尝试实现Uploadify，虽然它可以在我的本地服务器上运行，但是当我把它放到实时时它不起作用:(。它上传到数据库，但不上传实际的图像：）
我不知道如果它的文件权限有什么问题（怀疑它 - 因为我以前能够上传）或某种时间。问题是uploadify代码表示它完成了任务，并且除了放入实际图像之外它做的一切正确：）
我不知道为什么这不起作用。
这是add_pic页面（将信息发送到uploadify）
