Thunderbird Image Display Problem

To let your images displayed in your Thunderbird, making the connection / proxy settings may be one of the solutions for you. To make this experiment, all you need to do is, check your connection and proxy settings in the Thunderbird, and make some changes to it, to see if the images start working with you.

To change the proxy, following the steps below:

• Open Thunderbird
• Goto Tools -> Settings
• Choose Advanced icon on top
• Select Network & Disk Space tab
• In Connection frame, click on Settings button

Now you may be able to see different proxy options. You can try all of them, in my case, I chose Use system proxy settings to make my Thunderbird work fine with embedded images loading in it.

Hope this will help you displaying your email images in Thunderbird.
