Error Showing The Image on ReportPDF

I have table containing a blob field for a small logo image. I’m using Scriptcase 9.0.34.
On development environment there is no problem showing the image on pdf report. But after deployment on a server I got error.

[SIZE=16px]Fatal error[/SIZE][SIZE=16px]: Call to undefined function finfo_open() in [/SIZE][SIZE=16px]/home/demoportaranet/public_html/pdfprint_piform_ah/pdfprint_piform_ah_grid.class.php[/SIZE][SIZE=16px] on line [/SIZE][SIZE=16px]2299[/SIZE]

This pdfreport was working properly before on the same server. I have converted the project from Sc8 to SC9 and made a small change on the form.
I have no problem on development environment but on deployment there is a problem. I could not find a solution. Can it be a bug? Any advice!

Thanks
