Warning: imagejpeg(): Unable to open 'thumbnails/marching/years/2000/Miscellaneous/24left.jpg' for writing in /Library/WebServer/Documents/pictures/list.php on line 28
I'm looping through a directory and creating thumbnail images and in doing so, I get the error above for each image. The code I'm using to resize and create the image is below (it's an example from php.net) and the parameters are as follows:
$forcedwidth = 100
$forcedheight = 100
$sourcefile = 'marching/years/2000/Miscellaneous/24left.jpg'
$destfile = 'thumbnails/marching/years/2000/Miscellaneous/24left.jpg'
$imgcomp = 50
Both directories exist as does the source file. Which makes me wonder, will the library create a directory if it doesn't exist?
function resampimagejpg($forcedwidth, $forcedheight, $sourcefile, $destfile, $imgcomp) {
$g_imgcomp=100-$imgcomp;
$g_srcfile=$sourcefile;
$g_dstfile=$destfile;
$g_fw=$forcedwidth;
$g_fh=$forcedheight;
$g_is=getimagesize($g_srcfile);
if (file_exists($g_srcfile)) {
/////////////// Set Image Size ///////////////////
if(($g_is[0]-$g_fw)>=($g_is[1]-$g_fh)) {
/// Width is Greater Than Or Equal to Height
$g_iw=$g_fw;
$g_ih=($g_fw/$g_is[0])*$g_is[1];
} else {
/// Height is Greater than Width
$g_ih=$g_fh;
$g_iw=($g_ih/$g_is[1])*$g_is[0];
}
////////////// Create Thumbnail ///////////////////
$img_src=imagecreatefromjpeg($g_srcfile);
$img_dst=imagecreate($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, $g_dstfile, $g_imgcomp);
imagedestroy($img_dst);
} else
return false;
}
