On our our server we were using NETPGM to resize images. Unfortunately, this isn't working anymore and now I am looking for a way to resize images when they are uploaded. Any help or suggestions would be greatly appreciated. Here is the current code:

$ENV{PATH} .= ":/home/antiques/public_html/netpbm"; 
$pnmscale = "/home/antiques/public_html/netpbm/pnmscale";
$giftopnm = "/home/antiques/public_html/netpbm/giftopnm";
$ppmtogif = "/home/antiques/public_html/netpbm/ppmtogif";

        if ($filetype eq 'jpg') {


            ## THIS WILL RESIZE DISPLAY TO A THUMBNAIL
            my @fileparts = split(/\./, $Filename);
            my $outfile = $fileparts[0] . "-T." . $fileparts[1]; #IMAG
+E FACTOR: -ysize $thumbnail_height -xsize $thumbnail_width #cjpeg -qu
+altiy 5-95 optional quality
            ###### NETPBM THUMB CALL #####
            system("djpeg $SAVE_DIRECTORY\/$Filename | $pnmscale  -xsi
+ze $thumbnail_width  | cjpeg -quality 95 > $SAVE_DIRECTORY\/$item_id\
+_$outfile");
            ###### IMAGEMAGIK THUMB CALL #####
            #system("convert -sample x75 $SAVE_DIRECTORY\/$Filename $S
+AVE_DIRECTORY\/$item_id\_$outfile");


            ## THIS WILL RESIZE TO A DISPLAY IMAGE
            my @fileparts2 = split(/\./, $Filename);
            my $outfile2 = $fileparts2[0] . "-L." . $fileparts2[1]; #I
+MAGE FACTOR: -ysize $thumbnail_height -xsize $thumbnail_width
            ###### NETPBM DISPLAY CALL #####
            system("djpeg $SAVE_DIRECTORY\/$Filename | $pnmscale -xsiz
+e $display_width  | cjpeg > $SAVE_DIRECTORY\/$item_id\_$outfile2");
            ###### IMAGEMAGIK DISPLAY CALL #####
            #system("convert -sample x240 $SAVE_DIRECTORY\/$Filename $
+SAVE_DIRECTORY\/$item_id\_$outfile2");
            {system("mv $SAVE_DIRECTORY\/$item_id\_$outfile2 $SAVE_DIR
+ECTORY\/$item_id\_$Filename");}
            {system("rm $SAVE_DIRECTORY\/$Filename");}


        }
