在 IE 8 中显示 EMF 文件
我想在 IE 8 中显示一些（大约 5 到 10 个）EMF（增强型图元文件）文件。 我使用 ASP 从定义的文件夹中获取所有文件，并使用
这是正确的方法吗？图像加载速度非常慢，并且并非所有图像都加载。当我删除高度属性时，将加载图像。
你能帮我做对吗？

i would like to show some (about 5 to 10) EMF (Enhanced Metafile) Files in the IE 8.
I use ASP to get all Files from a defined Folder and show them with the <img src=""> Tag.
Some of the IMages are really big, so tried to reduce the size by setting its height to 100.
Is this the correct way? The Images load very slow and not all images are loaded. When i remove the height Attribute the Image is loaded.
Can you help me, do it right?

我不认为您可以在 HTML 中做太多事情来改变图像加载的速度。如果它们是大文件，则速度会很慢。
您可以尝试在 ASP 代码中创建较小版本的图像。我对ASP不熟悉，所以不知道有哪些图像处理功能。
I don’t think there’s much you can do in the HTML to change the speed at which the images are loaded. If they’re big files, they’re going to be slow.
You could maybe try to create smaller versions of the images in your ASP code. I’m not familiar with ASP, so I don’t know what image manipulation capabilities are available.
