Yes, it is easier to accomplish the task. Your task has two parts.
i) Convert your desired sheet to image using OnePagePerSheet Boolean attribute. This will work if your sheet is not very big (has 3/4 pages or less than 10 pages, etc.). See the example code (to domenstrate OnePagePerSheet option) in the document for your reference.
ii) If your worksheet is large, then you may refer to the example in the document that shows how to use Aspose.Cells to convert a worksheet that has several pages to render one image file per sheet page.
(please note, you may change the ImageType to “PNG”, “EMF” or “JPEG”, if you do not want images in “TIFF” format)
Once you render image(s) in Part1, then you may add the generated/rendered pictures to your desired sheet accordingly. See the document on how to add pictures in a worksheet for your reference.
Hope, this helps a bit.
