Use ViewImageAttachments
I want to use ImageViewer.so,I created two button with Work-AttachAFile one ,and Work-ViewImageAttachments one.
As a result,using Work-AttachAFile,I can attach Files.
And,using Work-ViewImageAttachments ,I can open the modal dialog.
But,when I click a file,it don't open.
What should I do to open that file?
