我试图在我当地的 prestashop 网站上重新生成所有缩略图。我得到了很多文件的这些错误：

Warning: imagecreatefrompng(): '/home/ll/Documents/www/ESI/img/p/2/5/8/258.jpg' is not a valid PNG file in /home/ll/Documents/www/ESI/classes/ImageManager.php on line 358

看起来他们已经损坏了......我该怎么办？

谢谢

此错误可能是因为文件是（真的！）JPEG 文件而不是 PNG 文件。

要解决此问题，您可以转到 PrestaShop 后台的“首选项”>“图像”并选择“JPG”而不是“PNG”。

此外，您可能需要重新考虑为您的产品图片选择 PNG 扩展名。在许多情况下，它会增加图像的权重而不提供任何改进。
