I am using absolute paths in my content which are being correctly outputted in generated HTML. However, the same gets converted to relative path in global rss feed which breaks images in feedburner.
I had tried the following with no success :
1). Setting base_path.
2). Used Pathologic filter and setting it to use absolute path. The Pathologic filter is also set to be the last filter for all Text formats.
Simply fix this issue in my Drupal 7 installation to complete the job.
