html5APP开发中图片的规格问题（移动端的图片尺寸可以怎样限制来加强页面的加载速度呢？）

使用HTML5做webAPP开发，发现平常PC端响应式WEB开发中使用的大图在WEBAPP开发中图片加载较慢，或者说损耗的内存太大。想请问一下移动端开发的图片尺寸是否有做什么限制呢，比如图片的尺寸大小，最大长度宽度，采用的图片格式等等的限制。例如文章页面的图片规格和列表页面的图片规格尺寸等有什么...

有一个做的差不多的app,现在想在每个页面初始化向服务器拿数据过来时，显示加载中，请稍等

我想的方法是每一个页面上最上面加一个加载中的，再到activity中加载后，隐藏加载中。这样工作量比较大，每个页面和每个activity都得改，每个activity都得判断，还有别的好的方法吗？
