DraftSight - Problems in DWG with JPG

In this dwg, you do not see the jpg images, which instead can be seen in autocad LT2011 or in nanocad.

(specifically in the right pane view is loaded)

The problem occurs in both 64-bit Windows8 64bit V1R3, V1R3 is the 32-bit version of Windows 7 32bit.

If I make different zoom and saved, you will sometimes see the jpg highlighted, and we can not see one of the other jpg, sometimes not.

If I select the portion of the drawing with the JPG (12 referring to 3 files on your computer) and I copy them into a new design in DraftSight, you see, just save the new file and reopen it, you do not see some images from JPG randomly

Can You solve ?
