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.
$im_out = ImageCreate($w1,$h1);
You will need to have the GD Library installed with your php.
Hope it helps,
