| thumbnail creation without save?
i have the code in place to create a tumbnail via php from an image..
but i want to create and DISPLAY it only the fly.. not save it to a directory..
i know that i can call:
img src = "myscript.php?arguments"
but i can't pass the filename, etc of the image i want to create the thumbnail from..
if i call the function directly in the img scr.. then the page is ONLY the thumbnail.. not contained in an image..
any insights on how to make a thumbnail for display on a page without saving it to a directory??

| Look at some of the image functions in PHP.
I use the following the ImageCopyResized and ImageJpeg functions to create thumbnails on the fly
Hope this helps

I have the proper workings of the functions.. it ust wasn't displaying..
but it turns out i had an error in the php age i was calling.. resulting in no image..

| certianly..
I call the image like:
IMG SRC="/makeimage.php?file=$file">
this means call the makeimage.php file with arguments that the php code needs:
makeimage.php :
code:
// set base image
$image = "/home/ercdvs/public_html/archive/$id/$file";
$image_info = getimagesize($image);
// image specifics
$too_big_diff_ratio = $image_info[0]/$max_width;
$new_img_width = $max_width;
$new_img_height = round($image_info[1]/$too_big_diff_ratio);
// determine image type
if($image_info[2] == "2") // JPEG
{
// This is for resizing JPG only
Header ("Content-type: image/jpeg");
$src_img = @imagecreatefromjpeg($image);
$dst_img = @imagecreatetruecolor($new_img_width,$new_img_height);
imagecopyresampled($dst_img, $src_img, 0, 0, 0, 0, $new_img_width, $new_img_height, $image_info[0], $image_info[1]);
imagejpeg($dst_img,'',90);
ImageDestroy($src_img);
ImageDestroy($dst_img);
}
This code takes the directory and filename of the big image.. and if it is a jpg, resizes to a max width of 100, and a hieght keeping with the image ratio
I need to write vrey similar code for gif, png, etc.. but 99.9% of m images are jpg.
feel free to copy and ask me any questions.
