Re: how to scale down image using ImageMagick?

Hi! This is what I do: if (!empty($picture)) { $size = GetImageSize ("pics/$picture"); if ($size[0] >= '175') { $width = '175'; $height = $size[1] * ($width / $size[0]); } else { $width = $size[0]; $height = $size[1]; } } echo "<img src=\"pics\$picture\" height=\"$height\" width=\"$width\">"; Fredrik A.
