OsCommerce Images Stretched - 贡献不起作用
在此网站（指向产品页面的链接：http://www.boatingsupplynow.com/product_info.php?cPath=979_1044&products_id=29943）上，图片显示为拉伸。
我已经应用了2种不同的图像拉伸贡献修复，似乎都不起作用。我在管理员端附上了我的图片设置的屏幕截图。请帮忙!!

我从来不喜欢图像拉伸“修复”的贡献。由于目录端不同页面中的图像大小不同，我一直更喜欢使用缩略图生成器。
将文件还原到您安装的两个加载项之前的版本后，请尝试this contribution。这样的包不是将图像拟合到特定尺寸，而是基于tep_image参数所需的尺寸，创建原始图像的重新采样和适当大小的副本。
这种经常被忽视的方法的另一个好处是，它还有助于节省带宽并减少页面加载时间。如果为产品上传2800px X 1400px图像，则该文件很可能是多MB图像。每次在目录端请求图像时，必须根据IMG标记的宽度和高度属性，在完成任何大小调整之前将完整文件下载到浏览器。使用缩略图的优点是每个缩略图的大小都会重新采样。因此，如果您的产品列表仅需要200px X 100px图像，则从您上传的2800px X 1400px图像制作200px X 100px图像。根据您的设置，您的图像可能在低KB范围内。
