Problems Rendering Jpg/Png

Question

I'm working on a project where we have tiff images and we break them into the individual pages, then we save those pages into memory streams in order to convert them into byte arrays so we can put that in a datatable column  and bind that table to a report that has a OLE blob field that renders the image.
The problem I'm have is that in  less than 1% of images the report fails to render the image and throw the following error:
Error in file tempReportPath.rpt: The request could not be submitted for background processing
I have analyzed the error and it only happens when the image is saved in the memory Stream and byte array as a compressed format: JPG/PNG/ Etc. Saving the image as a bitmap does not produce this problem, but the bitmap memory footprint makes it unusable for this project.
See code below.
Public Shared Function GetPicturesBytes(ByVal FileFullName As String) As Byte()()
        If Not IO.File.Exists(FileFullName) Then Return Nothing
        Dim tiff As Image = Image.FromFile(FileFullName)
        Dim dimension As New Imaging.FrameDimension(tiff.FrameDimensionsList(0))
        Dim frames As Integer = tiff.GetFrameCount(dimension)
        Dim Result(frames - 1)() As Byte
        For index As Integer = 0 To frames - 1
            tiff.SelectActiveFrame(dimension, index)
            Dim ms As New MemoryStream()
            tiff.Save(ms, System.Drawing.Imaging.ImageFormat.Jpeg)
            Result(index) = ms.ToArray()
            ms.Dispose()
        Next
       'This way because the file remains locked until the Image is disposed!!!
        tiff.Dispose()
        Return Result
    End Function
   Private Shared Function GetImgTbl(ByVal doc As DataTable, ByVal MRN As String,  ByVal patienName As String, ByVal refId As Integer) As DataTable
        Dim imgTbl As New DSDocs.DocsDataTable()
        For Each rw As DataRow In doc.Rows 'wrap.Documents.Rows
            Dim docs()() As Byte = GetPicturesBytes(docFullName)
            If IsNothing(docs) Then
                imgTbl.AddDocsRow(Nothing, (Doc not found!!!),more,Data)
                Continue For
            Else
                For index As Integer = 0 To docs.Length - 1
                    imgTbl.AddDocsRow(docs(index), other,table,data)
                Next
            End If
        Next
        Return CType(imgTbl, DataTable)
    End Function
The returned datable is used as report data source

Hi;
You don't mention which version of Crystal Reports you are using, or if you have installed the latest service packs.
We saw a similar issue recently, and our findings were:
- Crystal Reports 2008 with Service Pack 2 seems to handle images better than other versions
- Bitmap (BMP) files seem to work better than JPGs
Best Regards,
