+What's in here
+---------------
+The package ColImage contains encoders and decoders for the JPEG, GIF,
+and PNG formats that are compatible with VCL/C++Builder.
+
+How To Use It
+--------------
+1. Load the Project Group Image
+2. Build The LibImage Project
+3. Build the ColImage Project
+4. Copy ColImage.BPI, ColImage.BPL, ColImage.LIB to the appropriate
+directories. The standard location are the C++Builder /LIB directory
+for the .BPI and .LIB files and the /BIN directory for the .BPL file.
+5. Select COMPONENT|INSTALL|ADD and add ColImage.BPL
+
+At this point you should be able to use JPEG, GIF, and PNG files in
+design mode. Try creating a project and add an image control to it.
+If you double click on the Picture property in the object inspector
+you should be able to load these new image formats.
+
+To use these format in a project add the statement
+
+LoadPackage ("COLIMAGE.BPL") ;
+
+to your project's source module. Otherwise you may get errors messages
+about undefined file formats.
+
+
+*****A WORD OF CAUTION *****
+----------------------------
+When you build ColImage.BPI you cannot use the dynamic RTL. You must ensure
+that the Project|Options|Linker|Use debug libraries is not checked.
