我是这样使用的：

```
static void button_open_on(struct rtgui_object *object, struct rtgui_event *event)
{
	char path[32];
	struct rtgui_win	*win;
	rtgui_widget_t		*widgit = RTGUI_WIDGET(object);
	rtgui_rect_t		 rect = {0,20,320,240};

rt_memset(path, 0, sizeof(path));
	rtgui_filelist_view_get_fullpath(view, path, sizeof(path));
	if(rt_strstr(path, ".bmp") != RT_NULL|| 
		 rt_strstr(path, ".BMP") != RT_NULL||
		 rt_strstr(path, ".hdc") != RT_NULL||
		 rt_strstr(path, ".HDC") != RT_NULL||
		 rt_strstr(path, ".jpg") != RT_NULL||
		 rt_strstr(path, ".JPG") != RT_NULL)
		 
	{
		win = rtgui_win_create(RT_NULL,"图片浏览",&rect,RTGUI_WIN_STYLE_DEFAULT | RTGUI_WIN_STYLE_DESTROY_ON_CLOSE);
		
		rtgui_object_set_event_handler(RTGUI_OBJECT(win),win_event_handler);

if(path[0] != '�')
		image = rtgui_image_create(path,RT_FALSE);	
		
		rtgui_win_show(win,RT_TRUE);
	}
}
```

刚开始点击640x480的jpg格式图片直接崩溃，复位后我点击了一张30x30的jpg图标打开成功了。list_mem（）
total memory: 50704
used memory : 18052
maximum allocated memory: 48456
所以我觉得是内存不够导致打开jpg格式图片是直接崩溃。
