我制作了一个HTML电子邮件模板，该模板在大多数电子邮件阅读器中都可以正常工作，但是背景图像在Outlook 2007、2010和2013中没有显示.我该如何解决该问题?
I made an HTML Email Template that is working fine in most email readers, but the background images are not showing in Outlook 2007, 2010, and 2013. How can I solve the problem?
这是电子邮件的HTML:

推荐答案
电子邮件阅读器对背景图像的支持
Outlook 2007和更高版本仅支持两种显示背景图像的方法:
Email-reader support for background images
Outlook 2007 and later only supports 2 ways to display a bg image:
- 在body标签上使用HTML背景属性
- 在body标签上使用嵌入式背景图片样式
在这两种情况下，Outlook缩放图像的方式都不同于其他电子邮件阅读器，并且无法阻止bg图像的平铺.
In both cases, Outlook scales the image differently than other email readers, and there's no way to prevent the bg image from tiling.
因此，出于所有实际目的，背景图片并不是支持多种电子邮件阅读器的一种选择.相反，您需要处理前景图像(img标签).
So for all practical purposes, background images aren't an option for supporting a wide range of email readers. Instead, you'll need to make do with foreground images (img tags).
Outlook 2007 +，Gmail，Hotmail和Yahoo Mail不支持CSS定位.结果，无法在前景图像的顶部放置文本元素.
Outlook 2007+, Gmail, Hotmail, and Yahoo Mail don't support CSS positioning. As a result, there's no way to place a text element on top of a foreground image.
将电子邮件切成不同的区域(通常使用HTML表格)时，每个区域可以是文本元素或前景图像.但是，您不能在同一区域中同时拥有这两个元素(即，您不能有两个元素占据相同的空间或重叠).
When slicing up the email into different areas (typically using HTML tables), each area can either be a text element or a foreground image. But you can't have both in the same area (i.e., you can't have two elements occupying the same space or overlapping).
对于上面没有图像的区域，可以将电子邮件的那一部分剪切为单独的前景图像.
For areas where there's an image with no text on top of it, that part of the email can be cut as a separate foreground image.
对于图像顶部带有文字的区域，有3个选项:
For areas where there's an image with text on top of it, there are 3 options:
- 将文本剪切为图像的一部分.这会损害电子邮件的可用性，对于默认情况下禁用图片的用户(尤其是他们最初看不到文字的用户)而言，这尤其成问题.
- 将图像显示为背景图像，但要了解Outlook 2007+的用户将看不到该图像(平滑降级).
- 请勿尝试在任何电子邮件阅读器中显示背景图片.
适度地，选项#1通常是安全合理的.但是，如果大量使用它，则会导致电子邮件中图像与文本的比率很高，这可能会触发某些垃圾邮件过滤器.在大量使用选项#1之前，请先在各种垃圾邮件过滤器中测试电子邮件.
In moderation, option #1 is usually safe and reasonable. But when used heavily, it leads to a very high ratio of images to text in the email, which may trigger some spam filters. Before making heavy use of option #1, test the email in a variety of spam filters.
在继续使用选项#2或#3之前，您可能需要与设计人员将其清除(因为任何一种都会损害Outlook 2007+中的设计).在较大的图片中，设计电子邮件时应谨慎使用背景图像.向设计人员指出使用背景图片的影响可能会有所帮助.
Before proceeding with options #2 or #3, you may need to clear it with the designers (as either one compromises the design in Outlook 2007+). In the bigger picture, background images should be used sparingly when designing emails. It may be helpful to point out to the designers the impact of using background images.
