Move and Size with cells
To move and size a picture along with cell modifications, we need to set the IsMoveWithCell and IsSizeWithCell properties to true.
The following code example illustrates how to move and size a picture along with cells.
using (ExcelEngine excelEngine = new ExcelEngine())
{
IApplication application = excelEngine.Excel;
application.DefaultVersion = ExcelVersion.Xlsx;
IWorkbook workbook = application.Workbooks.Create(1);
IWorksheet worksheet = workbook.Worksheets[0];
//Adding a picture
FileStream imageStream = new FileStream("../../../Data/Image.png", FileMode.Open, FileAccess.Read);
IPictureShape shape = worksheet.Pictures.AddPicture(1, 1, 5, 3, imageStream);
shape = worksheet.Pictures.AddPicture(1, 5, 5, 7, imageStream);
//Set move picture with cell
shape.IsMoveWithCell = true;
//Set size picture with cell
shape.IsSizeWithCell = true;
//Hide the column
worksheet.HideColumn(5);
//Saving the workbook as stream
FileStream OutputStream = new FileStream("Output.xlsx", FileMode.Create, FileAccess.ReadWrite);
workbook.SaveAs(OutputStream);
//Dispose streams
imageStream.Dispose();
OutputStream.Dispose();
}
using (ExcelEngine excelEngine = new ExcelEngine())
{
IApplication application = excelEngine.Excel;
application.DefaultVersion = ExcelVersion.Xlsx;
IWorkbook workbook = application.Workbooks.Create(1);

Adding Images from External Link
An image can be added to a worksheet as an external link without downloading the original image. The picture will be downloaded every time the spreadsheet is opened in Microsoft Excel. The image is not physically embedded into the Excel document, but points to a web resource. Refer to the following code snippet.
using (ExcelEngine excelEngine = new ExcelEngine())
{
IApplication application = excelEngine.Excel;
application.DefaultVersion = ExcelVersion.Excel2013;
IWorkbook workbook = application.Workbooks.Create(1);
IWorksheet worksheet = workbook.Worksheets[0];
//Add image from the specified url at the specified location in the worksheet
worksheet.Pictures.AddPictureAsLink(1, 1, 5, 7, "https://cdn.syncfusion.com/content/images/company-logos/Syncfusion_Logo_Image.png");
//Saving the workbook as stream
FileStream stream = new FileStream("ExternalImage.xlsx", FileMode.Create, FileAccess.ReadWrite);
workbook.SaveAs(stream);
stream.Dispose();
}
using (ExcelEngine excelEngine = new ExcelEngine())
{
IApplication application = excelEngine.Excel;
application.DefaultVersion = ExcelVersion.Excel2013;
IWorkbook workbook = application.Workbooks.Create(1);
IWorksheet worksheet = workbook.Worksheets[0];
//Add image from the specified url at the specified location in the worksheet
worksheet.Pictures.AddPictureAsLink(1, 1, 5, 7, "https://cdn.syncfusion.com/content/images/company-logos/Syncfusion_Logo_Image.png");
//Save workbook
workbook.SaveAs("ExternalImage.xlsx");
}
Using excelEngine As ExcelEngine = New ExcelEngine()
Dim application As IApplication = excelEngine.Excel
application.DefaultVersion = ExcelVersion.Excel2013
Dim workbook As IWorkbook = application.Workbooks.Create(1)
Dim worksheet As IWorksheet = workbook.Worksheets(0)
'Add image from the specified url at the specified location in the worksheet
worksheet.Pictures.AddPictureAsLink(1, 1, 5, 7, "https://cdn.syncfusion.com/content/images/company-logos/Syncfusion_Logo_Image.png")
