This comes down to browser image support; it looks like the only mainstream browser that supports tiff is Safari:
这归结为浏览器图像支持；看起来唯一支持 tiff 的主流浏览器是 Safari：

Where are you getting the tiff images from? Is it possible for them to be generated in a different format?
你从哪里得到 tiff 图像？它们是否可以以不同的格式生成？
If you have a static set of images then I'd recommend using something like PaintShop Proto batch convert them, changing the format.
如果您有一组静态图像，那么我建议您使用PaintShop Pro 之类的工具来批量转换它们，更改格式。
If this isn't an option then there might be some mileage in looking for a pre-written Java applet (or another browser plugin) that can display the images in the browser.
如果这不是一个选项，那么寻找可以在浏览器中显示图像的预先编写的 Java 小程序（或其他浏览器插件）可能会有一些麻烦。

I found this resource that details the various methods: How to embed TIFF files in HTML documents

As mentioned, it will very much depend on browser support for the format. Viewing that page in Chrome on Windows didn't display any of the images.
如前所述，这在很大程度上取决于浏览器对格式的支持。在 Windows 上的 Chrome 中查看该页面未显示任何图像。
It would also be helpful if you posted the code you've tried already.
如果您发布已经尝试过的代码，这也会很有帮助。

Tiff images can be displayed directly onto IE and safari only.. no support of tiff images on chrome and firefox. you can encode the image and then display it on browser by decoding the encoded image to some other format. Hope this works for you
Tiff 图像只能直接显示在 IE 和 safari 上。不支持 chrome 和 firefox 上的 tiff 图像。您可以对图像进行编码，然后通过将编码的图像解码为其他格式将其显示在浏览器上。希望这对你有用

You can try converting your image from tiff to PNG, here is how to do it:
您可以尝试将图像从 tiff 转换为 PNG，方法如下：
import com.sun.media.jai.codec.ImageCodec;
import com.sun.media.jai.codec.ImageDecoder;
import com.sun.media.jai.codec.ImageEncoder;
import com.sun.media.jai.codec.PNGEncodeParam;
import com.sun.media.jai.codec.TIFFDecodeParam;
import java.awt.image.RenderedImage;
import java.io.ByteArrayInputStream;
import java.io.ByteArrayOutputStream;
import java.io.InputStream;
import javaxt.io.Image;
public class ImgConvTiffToPng {
public static byte[] convert(byte[] tiff) throws Exception {
byte[] out = new byte[0];
InputStream inputStream = new ByteArrayInputStream(tiff);
TIFFDecodeParam param = null;
ImageDecoder dec = ImageCodec.createImageDecoder("tiff", inputStream, param);
RenderedImage op = dec.decodeAsRenderedImage(0);
ByteArrayOutputStream outputStream = new ByteArrayOutputStream();
PNGEncodeParam jpgparam = null;
ImageEncoder en = ImageCodec.createImageEncoder("png", outputStream, jpgparam);
en.encode(op);
outputStream = (ByteArrayOutputStream) en.getOutputStream();
out = outputStream.toByteArray();
outputStream.flush();
outputStream.close();
return out;
}
