基于爬虫的网络图片预览器
·
1，第一个文本框可以直接复制网络图片地址，点击加载可以预览;点击转换图片可以下载，第二个文本框若为目录，图片会自动名称，为具体图片名称，以图片名称为准。
2，双击鼠标可以切换图片，不过必须有data.txt，里面必须有图片的地址，这些图片并没有下载，必须点击转换图片才会下载。
3，左键可以拖动图片到任意位置。
4，滑轮可以缩放图片。
5，文本框皆支持拖入路径的操作。
6，也可以直接拖入本地图片预览，本地图片不支持下载。
7，本地图片可以直接拖入中间区域，也可以拖入文本框后，点击加载，效果一致。
8，data.txt网络图片地址可以支持自己添加，将网络图片地址复制进去复制进去，不过每个图片地址必须单独为一行。如果不喜欢这些图片，可以将数据删除，重新手动添加。
9，点击switch开关时，会默认按照每六秒切换一张图片。
10，修改间隔时间后，必须为整数，会按照修改时间的间隔切换图片。
11,添加特定情况下滚轮刷新图片。
