+The following 4 steps to adding a new image format to blender, its
+probably easiest to look at the png code for a clean clear example,
+animation formats are a bit more complicated but very similar:
+
+Step 1:
+create a new file named after the format for example lets say we were
+creating an openexr read/writer  use openexr.c
+It should contain functions to match the following prototypes:
+
+struct ImBuf *imb_loadopenexr(unsigned char *mem,int size,int flags);
+/* Use one of the following depending on whats easyer for your file format */
+short imb_saveopenexr(struct ImBuf *ibuf, FILE myfile, int flags);
+short imb_saveopenexr(struct ImBuf *ibuf, char *myfile, int flags);
+
+/* Used to test if its the correct format
+int IMB_is_openexr(void *buf);
+
+Step 2: 
+Add your hooks to read and write the image format these go in
+	writeimage.c and readimage.c  just look at how the others are done
+
+Step 3: 
+Add in IS_openexr to blender/source/blender/imbuf/IMB_imbuf_types.h
+
+Step 4: 
+Add any external library info to the build process.
