I tried the above approach on catalog item record on icon field, the image is getting attached correctly on the record and shown correctly however the the icon field has broken image. Any solution for the same?

[hammad ul aziz2]

@Rasmita can show me what it looks like? Maybe try reducing the image resolution/size!

Hi Hammad, 
What changes would be necessary to add this as an attachment to the record?
