   I am trying to pull images from this pdf: http://www.4dwebdesign.com/uploads/5238.pdf

As you can see, there is at least one image on the first page. However, the following code says there are no images on the first page:

int[] intImageTypes = new int[4];
                                                int intFileHandle = qp.DAOpenFile(strTempTargetPath + "/" + e.FileName, "");
                                                int intTotalPages = qp.DAGetPageCount(intFileHandle);
                                                for (int k = 0; k <= intTotalPages; k++)
                                                {
                                                    int intPageHandle = qp.DAFindPage(intFileHandle, k);
                                                    int intImageList = qp.DAGetPageImageList(intFileHandle, intPageHandle);
                                                    int intImageCount = qp.DAGetImageListCount(intFileHandle, intImageList);
                                                    for (int i = 0; i < intImageCount; i++)
                                                    {
                                                        int intImageType = qp.DAGetImageIntProperty(intFileHandle, intImageList, i, 400);
                                                        int intImageWidth = qp.DAGetImageIntProperty(intFileHandle, intImageList, i, 401);

                                                        int intImageHeight = qp.DAGetImageIntProperty(intFileHandle, intImageList, i, 402);
                                                        double intImageLeft = qp.DAGetImageDblProperty(intFileHandle, intImageList, i, 501);
                                                        double intImageRight = qp.DAGetImageDblProperty(intFileHandle, intImageList, i, 503);
                                                        double intImageTop = qp.DAGetImageDblProperty(intFileHandle, intImageList, i, 502);
                                                        double intImageBottom = qp.DAGetImageDblProperty(intFileHandle, intImageList, i, 508);
                                                        intImageTypes[intImageType] += 1;
                                                    }
                                                }

	Never mind - read the documentation on DAFindPage and saw that they are one based, not zero based.
