I have used aspose.pdf for converting pdf to jpg, so can view pdf files as thumbnails
I followed this link to do: http://www.aspose.com/docs/display/pdfnet/Generate+Thumbnail+Images+from+PDF+Documents
but I have issue in performance as I have to view more than 500 file in one click.
so, the page is very slow and go to timeout error.
Any solution please?
