Python实现图片浏览器

Python实现图片浏览器

支持浏览多种常见图片格式：JPG, JPEG, PNG, GIF, BMP, TIFF, WEBP

通过"打开文件夹"按钮选择任何包含图片的文件夹

灵活的排序选项：

按时间排序（新→旧或旧→新）

按文件名排序（A→Z或Z→A）

键盘快捷键支持（左右箭头切换图片，Delete删除图片，F5刷新）

显示文件名和修改时间。当图片尺寸小于或等于显示区域时，会按原尺寸显示；只有当图片尺寸大于显示区域时，才会按比例缩放。同时，文件名标签会显示图片的原始尺寸，让你知道图片的实际大小。

运行效果

本程序要使用Pillow库的Image和ImageTk模块，它是第三方库，需要安装Pillow库（Pillow是PIL的一个分支，提供了更好的维护和更新）。详情可见https://blog.csdn.net/cnds123/article/details/126141838
