推荐答案

A .ICO 文件可以包含多张照片。因此，的favicon.ico 文件，你可能包含一个16×16的图片的和的一个32x32的图片。

A .ico file can contain several pictures. Therefore, the favicon.ico file you get may well contain a 16x16 picture and a 32x32 picture.

您可以使用 icotool 命令行工具来分析 .ICO 文件：

You can use the icotool command line tool to analyze a .ico file:

# On Ubuntu
sudo apt-get install icoutils
icotool -l favicon.ico
--icon --index=1 --width=16 --height=16 --bit-depth=32 --palette-size=0
--icon --index=2 --width=32 --height=32 --bit-depth=32 --palette-size=0
--icon --index=3 --width=48 --height=48 --bit-depth=32 --palette-size=0
# 3 pictures in this favicon.ico file

在Windows上，当你打开一个 .ICO 使用默认浏览器文件（只需双击该文件），观众让你通过包含在多个图片浏览文件。它不打印它们的分辨率，但至少你有一个关于正在发生的事情与你的奇怪的行为线索。

On Windows, when you open a .ico file with the default viewer (just double-click the file), the viewer let you navigate through the multiple pictures contained in the file. It does not print their resolution, but at least you have a clue about what is going on with your strange behavior.
