Hi, i followed the custom dam handler blog and was able to achieve what was mentioned in that. My requirement is that i need to get thumbnails created for Doc and Xls files when any dam asset is uploaded. I have gone through the DAM UPDATE ASSET workflow and the steps in that just work fine for TXT, IMAGES and PDF files.
