Some images failed to render when importing a word document into Confluence. It appears like below in Confluence page instead:

!worddav2af3a86a0e4f672f7989b394094b0737.png|height=157,width=301!
!worddav8bff63f9ae5c90b10a5ed5563c11cf9c.png|height=244,width=427!

These images however exist when checked from the attachments list.

Workaround:

Insert these images into Confluence page manually through Insert > Image.

This involves manual task and therefore it's best if we could find out the root cause of the problem and get it fixed.
