Attachment Provider with Icons on Task Pages

Hi All,

I have a requirement for a workflow where attachment Icons are needed.

  1. App admin logs in to first page and attaches files(.pdf, word, excel etc)

  2. Task will be navigated to next user with a screen which contains image-links to the attachments attached by admin in step1.

  3. All files should be stored in server.

Kindly let me know the best possible approach for this, as any samples would be really helpful if you have it handy sine I am a beginner in CAF.
