Question

I need to convert animated GIF to static in PHP. I mean e.g. use its first frame. Any idea how to do that ?

Answer 1

“Stripping” the GIF of animation can be done by converting it to another format and then back again. PNG is a good candidate for this “other format”, since it is non-lossy, unlike JPEG. Using PHPs GD functions, and outputting a PNG instead of a GIF:

header('Content-type: image/png');
imagepng(imagecreatefromgif($file));

This might work (haven’t tested) if PHP/GD doesn’t support animated GIFs (I don’t think it does); and it will output the image in GIF format, unlike the above snippet:

header('Content-type: image/gif');
imagegif(imagecreatefromgif($file));

If that won’t work, and output in GIF format is essential, this will:

$img1 = imagecreatefromgif($file);
$size = getimagesize($img1);
$img2 = imagecreatetruecolor($size[0], $size[1]);
imagecopy($img2, $img1, 0, 0, 0, 0, $size[0], $size[1]);
header('Content-type: image/gif');
imagegif($img2);
