I do use https://github.com/blueimp/jQuery-File-Upload for file uploads.

In the spec of this jQuery plugin, you can read:

Preview images can be loaded and displayed for local image files on browsers supporting the URL or FileReader interfaces.

IE8 is not HTML5 compliant thus not compatible with FileReader. You should use flash or friends to achieve that.

Firefox is HTML5 compliant...
