When I am uploading an image I use Image class to resize original photo to several dimensions and save each image variation to separate file. Now I got request to put a watermark on images. Everything is simple and fine using Image::watermark() method, but I run into some problems. My image processing goes like this: 1. grab and load the uploaded photo
2. put the watermark on this photo
3. crop and resize watermarked photo to desired new dimension(s) and save to file(s) My code is:

//if watermark checked then add watermark to original uploaded photo and overwrite it
if($watermark=="true") 
{
    Image::load($file)
         ->config('quality', 100)
         ->watermark(DOCROOT.'assets/img/logofoot.png', 'top left', 20)
         ->save($file);
}

//create 3 different image sizes from watermarked photo
Image::load($file)
            ->config('quality', 100)
            ->crop_resize($neww1, $newh1)
            ->save($uploaddir . DIRECTORY_SEPARATOR . $newname1);
Image::load($file)
            ->config('quality', 100)
            ->crop_resize($neww2, $newh2)
            ->save($uploaddir . DIRECTORY_SEPARATOR . $newname2);
Image::load($file)
            ->config('quality', 100)
            ->crop_resize($neww3, $newh3)
            ->save($uploaddir . DIRECTORY_SEPARATOR . $newname3);

This works, but sometimes I get black images when crop/resizing watermarked image into smaller dimensions. Not always but only sometimes. The original watermarked photo is fine, but smaller versions I create afterwards are black... Why is this happening? If I skip watermarking uploaded image (first if clause) then everything is fine, no black images! Thanks,
