[SOLVED] Firefox not displaying JPEG images
http://forums.gentoo.org/viewtopic-t-817165-start-0.html
For upgrading from jpeg-6b to jpeg-7 you do `revdep-rebuild --library libjpeg.so.62`
For upgrading from jpeg-7 to jpeg-8 you do `revdep-rebuild --library libjpeg.so.7`
试了后不能解决我的问题，谁知道原因，希不惜赐教。

下面是一些信息：

$ firefox bruceLee.jpg

The image “file:///home/mg/Mine/images/bruceLee.jpg” cannot be displayed, because it contains errors.

$ display bruceLee.jpg

终于可以用firefox打开图片了，
mozilla-firefox-3.5.8 -> 3.6.3,
net-libs/xulrunner-1.9.1.8 -> 1.9.2.3-r1,
dev-libs/nss-3.12.5 -> 3.12.6-r1,
dev-libs/nspr-4.8 -> 4.8.4.
估计是net-libs/xulrunner-1.9.1.8问题引起的。
