        asposepdfcloud "github.com/aspose-pdf-cloud/aspose-pdf-cloud-go/v25"
    )

    func AppendPageStampImage(pdf_api *asposepdfcloud.PdfApiService, documentName string, outputDocument string, imageFileName string, pageNumber int32, width float64, height float64, remoteFolder string) {
        // Append image stamp to page of the PDF document.
        uploadFile(pdf_api, documentName)
        uploadFile(pdf_api, imageFileName)

        args := map[string]interface{}{
            "folder": remoteFolder,
        }

        stamp := asposepdfcloud.ImageStamp{
            Background:          true,
            HorizontalAlignment: asposepdfcloud.HorizontalAlignmentCenter,
            VerticalAlignment:   asposepdfcloud.VerticalAlignmentCenter,
            Opacity:             1,
            Rotate:              asposepdfcloud.RotationNone,
            RotateAngle:         45,
            Width:               width,
            Height:              height,
            Zoom:                1,
            FileName:            path.Join(remoteFolder, imageFileName),
        }
        _, httpResponse, err := pdf_api.PostPageImageStamps(documentName, pageNumber, []asposepdfcloud.ImageStamp{stamp}, args)
        if err != nil {
            fmt.Println(err.Error())
        } else if httpResponse.StatusCode < 200 || httpResponse.StatusCode > 299 {
            fmt.Println("appendStampImage()): Failed to append image stamp to the document.")
        } else {
            fmt.Println("appendStampImage(): image stamp '"+imageFileName+"' appended successfully pn page", pageNumber, " to the document '"+documentName+"'.")
            downloadFile(pdf_api, documentName, outputDocument, "add_image_stamp_")
        }
