I had drawings setup in Autocad 2006 where were worked on using Autocad 2007. When I try and work on these drawings again in 2006 I loose the images in .bmp format. It will not allow me to detach the image, where in turn will not allow me to bring it back in as it believes it is still in the drawing. So I am unsure if it has anything to do with using 2007 and then converting the file back to 2004 to use in 2006.......lost for ideas. Has anyone else had these sort of problems. Any help would be appreciated as I need to issue drawing to my client soon. T-Bone
