I have a site that allows users to upload images to the report. The users can upload as many images as they want and the images get appended to the report.
The report viewer initially contains a report and the users images are appended at the button of the report. The way I append the images: I have created a one page report that has an image in the middle of the report. I iterate through all the image paths and add a new report for each image.
Here is an example of when the report processes the error. When a user adds 1 image and renders the report the report view looks great but once they add more images and try to render the report the report view crashes.
Below is the Error and Stack Trace:

else

// we need to clone the image for thread safety
image = ReportDataMethod.GetImage(imageFile);
}
else
{
image = Reporting.EFV.Reports.ReportDataMethod.GetImageFromResource(fileResourceName);
}
double width = image.Width / image.HorizontalResolution;
double height = image.Height / image.VerticalResolution;
SizeU size = new SizeU(Unit.Inch(width), Unit.Inch(height));

rpt.PageSettings.PaperSize = size;
pictureBox1.MimeType = "image/png";

}
}
Here is the way I append the images in the resolver
// Add File Attachment to report
// Attach image files as pages
// Gets the paths
var pngImagePaths = ReportDataMethod.GetFilePaths(eFormID);
if (pngImagePaths != null)
{
var pageCountID = 1;
foreach (var imagePath in pngImagePaths)
{
// Add cover page (Eventually we will add this to all E-Forms
// Add scanned file
// note that setting filePath or File Resource Name to null will
// cause the preview to crash on reload
PDFToImageParameters fileParams = new PDFToImageParameters()
{
FilePath = imagePath,
FileResourceName = "",
ImageExists = true,
IsEmbeddedResource = false,
PageCount = pageCountID
};
var fileReport = UpdateScannedImageReportWithParams(eFormID, pageCountID == 1 ? "File Attachment" : String.Empty, pageCountID++, fileParams);
book.Reports.Add(fileReport);
}
}
Any help would be appreciated.
Thanks!
