You may not see all your rasters on your drawing if you have opened your drawing on another computer, if you have changed computers or if the images were moved or deleted from the computer.
Please Note: If you have moved image folders and files you should move them back to the original location (or to the same location on a new computer).
If you are using the same drawing on different computers and you require the images to be visible then the images need to be saved on both computers in the same place. For example: Computer number 1 has images folder in this path: C:\Documents and Settings\[USERNAME]\Images\ then Computer number 2 has to have the exact same path
To avoid “missing” rasters, place the images closer to the root like C:\Images\ on both computers and be sure to copy the images into this folder whenever you add new images to the drawing.
If you are unsure of where the images were, you can take a look at your drawing to view the file location by following these steps:
