# Raster Images [GstarCAD 2021](Help%20System/GSTARCAD/2021/Index.md) → [User Guide](Help%20System/GSTARCAD/2021/User%20Guide/(User%20Guide).md) Raster images consist of a rectangular grid of small squares or dots known as pixels. Raster images can be added in a drawing by inserting image files or pasting as OLE. Raster images can be copied, moved, and support the follow formats: BMP(.bmp, .dib, .rle) CALS-I(.gp4, .mil, .rst, .cg4, .cal) JPEG(.jpg, .jpeg) PCX(.pcx) PNG(.png) TIFF(.tif or .tiff) ![](Help%20System/GSTARCAD/2021/assets/GCAD_GUG/GCAD_GUG/pic/Raster%20images%201.jpg) [Attach and Detach Raster Images](Help%20System/GSTARCAD/2021/User%20Guide/Raster%20Images/Attach-and%20Detach%20Raster%20Images.md) A raster image file can be attached and detached to a drawing file. Once an image is detached, all instances of the image are removed from the drawing. [Show and Hide Raster Image Boundaries](Help%20System/GSTARCAD/2021/User%20Guide/Raster%20Images/Show%20and%20Hide%20Raster%20Image%20Boundaries.md) You can control whether the clipping boundaries of a raster image are displayed or hidden by performing the command IMAGEFRAME and setting up the values 1 or 2\. [Clip Raster Images](Help%20System/GSTARCAD/2021/User%20Guide/Raster%20Images/Clip%20Raster%20Images.md) If you want to display only parts of images, you can clip the images by IMAGECLIP with polygonal, rectangular or closed polyline.
