当局引用时，IE中的32位深度jpg图像问题 [英] 32 bit depth jpg images problem in IE when referenced locally
问题描述
我们有一个webbapplication，它会拍摄一张将上传并调整大小的图片。
无论深度如何，我们使用的resize-library都保存了32位深度的所有图片。
We have an webbapplication that takes an image that will be uploaded and resized. The resize-library we used saved all pictures with 32-bit depth whatever the depth was before.
我们有一个在线客户端可以通过以下方式查看图片一个html文件，一切都很好。所有图片都显示正确。
We have an online client that can view the pictures via an html-file and all is fine there. All pictures are shown correctly.
问题：
我们还有一个vb-winform应用程序可以下载图片并在webbrowser控件中本地显示在html文件中。但是这里所有的图片都被拒绝（没有渲染），只有红十字。如果我们在本地创建一个带有img-tags的静态html文件，它就是一样的。所有具有32位深度的图片都显示为红色十字。
The problem:
We also have an vb-winform application that download the pictures and show them in an html-file locally in an webbrowser control. But here all pictures are rejected (not rendered), just the red cross. If we create an static html-file with img-tags in them locally, its the same. All pictures that has 32-bits depth are shown as red crosses.
如果我们重新保存24位深度的图片，它会再次神奇地起作用。所以当然是我们的解决方法，让resize-library保存所有24位深度的图片。
If we resave the pictures with 24-bits depth it magically works again. So ofcourse that was our "workaround", let the resize-library save all pictures with 24-bits depth instead.
摘要：
32位jpg文件在联机时在IE中显示正确，但在本地html文件中本地引用时则不正确。 （对于winxp和windows7上的IE8都是如此）。在mozilla中打开的同一个本地html文件显示确定。
Summary:
32-bits jpg files shows correct in IE when online but not when referenced locally in a local html-file. (This is true for IE8 on both winxp and windows7). The same local html-file opened in mozilla showed OK.
问题：
我已经google了很多但是没找到关于这个问题的任何事情。这是IE8中的错误吗？
Question: I have googled this a lot but has not found anything about this "problem". Is this a bug in IE8?
推荐答案
我对自己的网络应用程序有完全相同的问题。
I have exactly the same problem with my own webapplication.
这不仅是IE8的一个问题，而且许多其他浏览器也无法支持jpg文件的32位深度。
This isn't only a problem from IE8 but a lot of other browsers can't support the 32 bit depth on a jpg file.
暂时没有解决方案。尝试以24位深度转换图片。或者等待即将推出的IE9.0。这是你唯一的方式。
For the while, no solution exist. Try to convert your picture in a 24 bit depth. Or wait for IE9.0 that comes soon. It's the only way you have.
