避免拉伸照片

Question

如何避免照片拉伸？PHP从文件夹中随机选择2张照片并使用它们显示echo.但是现在,所有照片都是纵向的.

<?php if(!empty($images)) {
    $rand_key = array_rand($images, 1);
    $src = $images[$rand_key];
    echo "<img class=\"flickrphoto\" src='".$src."' align='absmiddle'>";

    unset($images[$rand_key]);
    $rand_key = array_rand($images, 1);
    $src = $images[$rand_key];
    echo "<img class=\"flickrphoto\" src='".$src."' align='absmiddle'>";
} else {
    echo 'Error';
} ?>

而CSS:

.flickrphoto {
    max-width: 100px;
    max-height: 100px;
    overflow: hidden;
}

**编辑**
当前代码:

   // protrait calculations;
    $size = getimagesize($images_folder_path);
    if($size[0] < $size[1]) {
        $orientation = 'portrait';
    } else {
        $orientation = 'landscape';
    }

我只是检查方向是否是protrait并添加一个css类;

<?php if(!empty($images)) {
$rand_key = array_rand($images, 1);
$src = $images[$rand_key];

// protrait calculations;
$fullpath = // statement to fetch the path on the server
$size = getimagesize($fullpath);
if($size[0] < $size[1]) {
   $orientation = 'portrait';
} else {
   $orientation = 'landscape';
}

echo "<img class=\"flickrphoto ". $orientation ."\" src='".$src."' align='absmiddle'>";

unset($images[$rand_key]);
$rand_key = array_rand($images, 1);
$src = $images[$rand_key];
echo "<img class=\"flickrphoto\" src='".$src."' align='absmiddle'>";
} else {
    echo 'Error';
} ?>

在你的CSS这样的事情:

img.flickrphoto {
    max-width: 100px;
    max-height: 100px;
    overflow: hidden;
}
img.flickrphoto.portrait {
    max-width: 50px;
}
