In this tutorial, you will learn how to fix the Upload Media Exception when using Sitecore CMS. Recently, after upgrading Sitecore v7.2 to v7.5, whenever a content editor tried to upload an image, an editor reported that the image picker did not work:

sitecore 7.5 upgrade image browse error

They would receive this error:

The fix to get the image picker working again is simple. Sitecore is complaining that it doesn't know about the System.Runtime assembly. To fix this all you need to do is register the assembly in your web.config and everything should be up and running again. In order to do this, open your websites web.config and navigate to the section.

Add a reference to System.Runtime. Next time you try to open your image picker it should load as expected:

sitecore_75_upgrade_image_browse_error_1

Simple fix. Happy Coding 🤘
