Re: Resizing an image (dynamic)

try this code snippet, this is designed for a file on disk but this should help function thumb($image,$divider=4,$quality=70) { // If someone tries to change directories, bomb out if(ereg("/", urldecode($image))) { die; } Header("Content-type: image/jpeg"); $imagefile = "images/".urldecode($image).""; $src_img = imagecreatefromjpeg($imagefile); $new_w = imagesx($src_img)/$divider; $new_h = imagesy($src_img)/$divider; $dst_img = imagecreate($new_w,$new_h); imagecopyresized($dst_img,$src_img,0,0,0,0,$new_w,$new_h,imagesx($src_img),imagesy($src_img)); imagejpeg($dst_img,'',$quality); ImageDestroy($dst_img); ImageDestroy($src_img); } Lauri Vain wrote: > Hello, > > I have to resize an image to reduce the loading time (there will be thumbnails, > which have to be resized, and there will be full sized images). > > Now, the images that will be inserted into the DB have the dimensions height=300 > and width=400.
