The insert graphics utility located under the insert menu on the menu bar 
fails to properly insert all Macintosh Pict files into Open Office 
presentations.   I included two screenshots of the issue.  The first 
screenshot shows a .jpg and an .pct image side by side in adobe photo shop.  
The image size of both pictures is 200x146.  Notice that the .pct image is 
identical to the .jpg file.  The next screenshot show an example of the 
insertion issue in open office presentation.  Thank You.

1.Opened Open Office 1.1.0 Presentation;
2.Create an empty presentation;
3.Choose a blank slide;
4.Choose Insert -> Graphics from the file menu;
5.Select a .jpg file and insert it into a blank presentation;
6.Save the same .jpg file as a .pct file;
7.Insert the .pct file the same way as steps 4-5.
