[SOLVED] Problem with function

[craygo]

It's been a while since I have had to post a question here.  ;D I guess that's a good thing.

well I have a function that resizes a picture. I do not want to create a new picture I just want to resize it and display it. Problem I am having is that it does the first picture and stops there. I want to use this in a loop when I get the picture names from the database. It was not working so I took out the loop and just tried to put 2 pictures in manually and i get the same thing

[code]<?php
header('Content-type: image/jpeg');
function resampimagejpg($forcedwidth, $forcedheight, $sourcefile, $destfile, $imgcomp=0)
  {
  $g_imgcomp=100-$imgcomp;
  $g_srcfile=$sourcefile;
  $g_dstfile=$destfile;
  $g_fw=$forcedwidth;
  $g_fh=$forcedheight;

  if(file_exists($g_srcfile))
      {
      $g_is=getimagesize($g_srcfile);
      if(($g_is[0]-$g_fw)>=($g_is[1]-$g_fh))
          {
          $g_iw=$g_fw;
          $g_ih=($g_fw/$g_is[0])*$g_is[1];
          }
          else
          {
          $g_ih=$g_fh;
          $g_iw=($g_ih/$g_is[1])*$g_is[0];
          }
      $img_src=imagecreatefromjpeg($g_srcfile);
      $img_dst=imagecreatetruecolor($g_iw,$g_ih);
      imagecopyresampled($img_dst, $img_src, 0, 0, 0, 0, $g_iw, $g_ih, $g_is[0], $g_is[1]);
      imagejpeg($img_dst,'',90);
      imagedestroy($img_dst);
      imagedestroy($img_src);
      return true;
      }
      else
      return false;
  }
resampimagejpg("100", "100", "images/TEST.jpg", "");

resampimagejpg("100", "100", "images/SHOback_jpg.jpg", "");
?>[/code]

I tried it with and without the header and get the same thing. I have the $destfile variable in there because I used this for an upload script to create thumbnails and it works great. So I just took out the destination so I can just view it in the browser.

Thanks

Your going to have to call it from a image tag <img src='script.php?next=xxx'> in a different script! Because once you dump the first image, the browser waits for the EOF flag, once it's returned it stops reading, so you can't loop more than (1) image per (1) Content-Type header. So the browser only allows one content read up to EOF for any one Content-Type header.

Thanks that worked out great. Was not aware you could not do that with images.
