Use the following command from the Package Manager Console.

        localImagePath := "C:\\Samples\\sample.jpg"
        storageImageFile := "sample.jpg"

        outputFileName := "output_replace_images.pdf"
        imageId := "GE5TCMJQGUZDWMJZGMWDOMZSFQZDSOBMG42DK"

        AppSID := "****************" // Your Application SID
        AppKey := "************"     // Your Application Key

        pdfApi := asposepdfcloud.NewPdfApiService(AppSID, AppKey, "")

        args := map[string]interface{}{
            "folder":        storageTempFolder,
            "imageFilePath": filepath.Join(storageTempFolder, storageImageFile),
        }

        file, _ := os.Open(filepath.Join(localFolder, storageDocumentName))
        _, _, _ = pdfApi.UploadFile(filepath.Join(storageTempFolder, storageDocumentName), file, args)

        imageFile, _ := os.Open(localImagePath)
        _, _, _ = pdfApi.UploadFile(filepath.Join(storageTempFolder, storageImageFile), imageFile, args)

        _, httpResponse, err := pdfApi.PutReplaceImage(storageDocumentName, imageId, args)
        if err != nil {
            fmt.Println(err.Error())
        } else if httpResponse.StatusCode < 200 || httpResponse.StatusCode > 299 {
            fmt.Println("ReplaceImage()): Failed to replace image in the document.")
        } else {
            result_data, _, _ := pdfApi.DownloadFile(filepath.Join(storageTempFolder, storageDocumentName), args)
            fileName := path.Join(localFolder, outputFileName)
            f, _ := os.Create(fileName)
            _, _ = f.Write(result_data)
            fmt.Println("AppendImage(): image '" + storageImageFile + "' replaced successfully in the document '" + outputFileName + "'.")
        }
    }
 

Work with Images in PDF

Images make documents visually engaging and help break up large blocks of text, making them more attractive to readers. Photos, screenshots, or icons can add context to the content, making it more relatable and meaningful for the audience.
