解决方法
1、后台-系统-附件设置，添加bmp
2、includedialogselect_images_post.php 找到
- $sparr = Array("image/pjpeg", "image/jpeg", "image/gif", "image/png", "image/xpng", "image/wbmp");
- $sparr = Array("image/pjpeg", "image/jpeg", "image/gif", "image/png", "image/xpng", "image/wbmp", "image/bmp");
- $sparr = Array('image/pjpeg', 'image/jpeg', 'image/gif', 'image/png', 'image/xpng', 'image/wbmp');
- $sparr = Array('image/pjpeg', 'image/jpeg', 'image/gif', 'image/png', 'image/xpng', 'image/wbmp', 'image/bmp');
- (gif|png)
- (gif|png|bmp)
