In web design and development, pictures are one of the elements that often appear. However, when a web page contains a large number of high-definition images, it will significantly increase the page loading time and affect the user experience. To solve this problem, we can use image thumbnails to reduce the size of the original image, thereby increasing the loading speed of the page.
This article will introduce how to use PHP and Highslide to create image thumbnails. Highslide is a powerful JavaScript library for creating beautiful image thumbnails and image browsers. PHP is a widely used server-side scripting language that can be used to generate images and process files.
Step 1: Install Highslide
First, we need to install Highslide in our project. We can download the latest version of Highslide from the Highslide official website. Once downloaded, we can unzip Highslide into our project directory and include Highslide's JavaScript and CSS files in the
tag of the web page.Step 2: Create a thumbnail
Next, we need to create the original image as a thumbnail. For this we can use PHP’s GD library. The GD library is an image processing library that can be used to generate and scale images. We can use the following code to shrink the image to the specified size:
<?php // 配置原始图片路径和缩略图路径 $image_path = "images/my_image.jpg"; $thumb_path = "thumbs/my_thumb.jpg"; // 配置缩略图的大小 $thumb_width = 200; $thumb_height = 200; // 获取原始图片的信息 list($image_width, $image_height) = getimagesize($image_path); // 计算缩略图的比例 $thumb_ratio = $thumb_width / $thumb_height; $image_ratio = $image_width / $image_height; if ($thumb_ratio < $image_ratio) { $new_width = $thumb_width; $new_height = $new_width / $image_ratio; } else { $new_height = $thumb_height; $new_width = $new_height * $image_ratio; } // 创建缩略图 $thumb = imagecreatetruecolor($thumb_width, $thumb_height); $image = imagecreatefromjpeg($image_path); imagecopyresampled($thumb, $image, 0, 0, 0, 0, $new_width, $new_height, $image_width, $image_height); imagejpeg($thumb, $thumb_path, 75); ?>
The above code reduces the original image to the specified size and saves the generated thumbnail to the specified path.
Step 3: Add Highslide effect
Now, we have successfully created the thumbnail. In order to make the thumbnails more vivid and beautiful, we can add Highslide effect. To do this, we can use the following code:
<a href="images/my_image.jpg" class="highslide" onclick="return hs.expand(this)"> <img src="/static/imghwm/default1.png" data-src="thumbs/my_thumb.jpg" class="lazy" alt="My Image" title="点击查看大图" /> </a> <style> .highslide { display: block; margin-bottom: 20px; } .highslide img { border: 0; } </style> <script> hs.graphicsDir = 'highslide/graphics/'; hs.align = 'center'; hs.transitions = ['expand', 'crossfade']; hs.fadeInOut = true; hs.dimmingOpacity = 0.75; hs.addSlideshow({ interval: 5000, repeat: true, useControls: true, fixedControls: 'fit', overlayOptions: { opacity: 0.75, position: 'bottom center', hideOnMouseOut: true } }); </script>
The above code will convert our thumbnail into a Highslide effect. When the user clicks on the thumbnail, Highslide will display the original image with a beautiful animation and provide some useful controls such as playing slideshow, resizing and downloading.
Step 4: Create your own picture library
Now, we have successfully created a set of picture thumbnails using PHP and Highslide. We can repeat the above steps to create more thumbnails and combine them into a beautiful gallery. We can use the photo album plugin to create photo albums and display beautiful thumbnails and image galleries on the web page. When developing your own image library, we should make sure to use good programming practices, such as optimizing code, using caching, and using technologies such as CDN, to ensure the best performance and user experience.
Conclusion
In this article, we learned how to use PHP and Highslide to create image thumbnails and convert them into a beautiful image gallery. Using these technologies, we can improve our website's loading speed and user experience, and make our website more attractive and professional. We encourage readers to apply these technologies to their own web design and development, and to continuously improve and optimize their websites.

php把负数转为正整数的方法:1、使用abs()函数将负数转为正数,使用intval()函数对正数取整,转为正整数,语法“intval(abs($number))”;2、利用“~”位运算符将负数取反加一,语法“~$number + 1”。

实现方法:1、使用“sleep(延迟秒数)”语句,可延迟执行函数若干秒;2、使用“time_nanosleep(延迟秒数,延迟纳秒数)”语句,可延迟执行函数若干秒和纳秒;3、使用“time_sleep_until(time()+7)”语句。

php除以100保留两位小数的方法:1、利用“/”运算符进行除法运算,语法“数值 / 100”;2、使用“number_format(除法结果, 2)”或“sprintf("%.2f",除法结果)”语句进行四舍五入的处理值,并保留两位小数。

判断方法:1、使用“strtotime("年-月-日")”语句将给定的年月日转换为时间戳格式;2、用“date("z",时间戳)+1”语句计算指定时间戳是一年的第几天。date()返回的天数是从0开始计算的,因此真实天数需要在此基础上加1。

方法:1、用“str_replace(" ","其他字符",$str)”语句,可将nbsp符替换为其他字符;2、用“preg_replace("/(\s|\ \;||\xc2\xa0)/","其他字符",$str)”语句。

php判断有没有小数点的方法:1、使用“strpos(数字字符串,'.')”语法,如果返回小数点在字符串中第一次出现的位置,则有小数点;2、使用“strrpos(数字字符串,'.')”语句,如果返回小数点在字符串中最后一次出现的位置,则有。

php字符串有下标。在PHP中,下标不仅可以应用于数组和对象,还可应用于字符串,利用字符串的下标和中括号“[]”可以访问指定索引位置的字符,并对该字符进行读写,语法“字符串名[下标值]”;字符串的下标值(索引值)只能是整数类型,起始值为0。

在PHP中,可以利用implode()函数的第一个参数来设置没有分隔符,该函数的第一个参数用于规定数组元素之间放置的内容,默认是空字符串,也可将第一个参数设置为空,语法为“implode(数组)”或者“implode("",数组)”。
