让搜索引擎“看到”图片文字？ [英] letting a search engine 'see' image text?
问题描述
这可能是一个标准的答案，但它以前从未出现过
。
我有一个（ png）包含一些文字的图像（标有组合照片
会议的
），如果搜索引擎也可以找到那些
的嵌入式名称，它会很有用 - 没有多余地将它们放在可见的HTML
文本中。这样做的好方法是什么？
有些文字可以放在图片的'alt''标签上，我想这就是$ b $通过搜索检查b，但这可能有点长。假设我可以像垃圾邮件发送者那样使用白底白字......（： - /）我希望有一种可靠的方式来识别这种方式。 />

There''s probably a standard answer for this, but it''s never cropped up
for me before.
I have a (png) image that includes some text (a labelled group photo
of a conference), and it''d be useful if a search engine can find those
embedded names too -- without redundantly placing them in visible HTML
text. What''s a good way to do this?
Some of the text can go in the ''alt'' tag of the image, which I suppose
is checked by a search, but that could be a bit long. Suppose I could
use white-on-white like the spammers do... (:-/) I expect there''s a
recognized way, though.

想象一个使用音频浏览器的盲人。他看不到你的形象，但他的浏览器读取了页面的其余部分对他大声说。音频
浏览器还从ALT属性中读取文本。因此，您的图像的ALT属性应该包含足够的文本，以至少告知盲人
用户图像的含义。如果在没有引用图片中的文字的情况下无法完成，那么你应该引用ALT
属性中的文字。
这是为什么不应该使用图像来传达文字的原因之一。

Imagine a blind person using an audio browser. He can''t see your image,
but his browser "reads" the rest of the page aloud to him. The audio
browser also reads the text from ALT attributes. The ALT attribute for
your image should thus contain enough text to at least inform a blind
user what the image was about. If that cannot be done without quoting
the text in the image, then you should indeed quote the text in the ALT
attribute.
This is one reason why images should NOT be used to convey text.

是 - 只要搜索引擎做同样的事情......（我猜是这样，但是
是我原来的问题。）这个特定的图像可能不会对盲人用户使用很多，因为它只是将名字与面孔联系起来。
Yes -- as long as as search engine does the same... (I presume so, but that
was my original question.) This particular image would probably not be much
use to a blind user, as it simply associates names with faces.

完全同意，通常。在这种情况下，虽然a）图像被发送到
我注释，和b）文本必须紧密匹配
人 - 我不愿意'不信任浏览器。
谢谢，

Totally agreed, normally. In this case though a) the image was sent to
me annotated, and b) the text has to be closely placed to match the
people -- something I wouldn''t trust a browser to do.
Thanks,

But I don''t know if search engines would actually follow the longdesc-link.
这是问题 - 我找不到（文本或其他）浏览器
看到longdesc，所以也许它不太可能是一个搜索引擎，
。
我最终可能只需看看alt属性是否显示在
google ...
This is the problem -- I haven''t found a (text or otherwise) browser that
sees longdesc at all, so maybe it''s unlikely that a search engine would,
either.
I may eventually just have to see if the alt attribute shows up in a
google...
