Hi Dan,
I don't know about resizing it from blob, I usually store the image on the
server and just the file name in the database . But I use something like
this for resizing:
$size = GetImageSize($filenum);
$im_in = ImageCreateFromJpeg($filenum);
$h1=$h; //were $h is the height that you want the image to have. The same
you can specify a width and calculate the height.
$w1=$h1/($size[1]/$size[0]);
$im_out = ImageCreate($w1,$h1);
ImageCopyResized($im_out,$im_in,0,0,0,0,$w1,$h1,$size[0],$size[1]);
ImageJpeg($im_out,$filenum);
ImageDestroy($im_in);
ImageDestroy($im_out);
You will need to have the GD Library installed with your php.
Hope it helps,
Cami
