We have many problems with users using OOo 2.1 (and 2.0) editing RTF documents 
containing bmp images.
These images are lost after being modified.

The iter is this.
1) Creation of a new document without images, saving it as RTF.
2) Reopen document, add image from file (embedded) choosing a BMP image.
3) Save.
4) Reopen document, modify text.
5) Save.
6) Reopen document and the image is lost.

The image is visibile opening RTF with Word 2003.

Viewing RTF files, it seems that after point (3) the rtf file contains the 
image 2 times (one as pngblip and one as wmetafile8... i think for backward 
compatibility)
But after point (5) the rtf file contains image as wmetafile8 (rtf tag) but 
with the content of previous pngblip.

I'll attach the doc. at point (1), the bmp for point (2) and the doc. after 
point (3) and (5).
