PHP-显示来自Mysql的图像的缩略图

Question

I have a table in my mysql db that contains path for images. I want to display thumbnails of this images. Can you tell me what is the best solution for that. This is how i display the full size images from db:

<?php for($i=1; $i<=5; $i++)
{$query = mysql_query("SELECT * FROM photos WHERE product_id='".$i."'");
$row = mysql_fetch_array($query);
$t="img/";
$file = $t .$row[1];
echo "<li><a href=\"#\"><img src = " . $file . "></a></li>";
} ?>

Answer 1

调整css / html中图像的大小（错误）或制作一个以文件名作为输入的php脚本，然后返回缩小版本作为输出（更好）或将缩略图存储在服务器上（最好）

Answer 2

您可以使用此http://mightystuff.net/php-thumbnail-script

Answer 3

You should avoid having to resize the images using CSS or HTML. Before saving the images onto the server, you should use ImageMagick to resize it. Do you really want to store a bunch of 6MB images? If that's not feasible, then saving the images as is and pointing to the path would suffice. However, if you end up with hundreds or thousands of images, you'll want to explore a better option.

Answer 4

I agree with the approach of storing the file path (instead of the binary file itself).

So your question is "how do you create a thumbnail?"

The best answer is ImageMagick:
