asp.net - root address difference <a> href and img src -

is there difference between determining path <img src=""> , <a href=""> ?

i using same type of referencing root both of them , refer different places, in way :

<img src="/folder1/folder2/1.jpg" >    

refers parent folder of current folder , searches folder1 there !

but :

<a href="/folder1/folder2" > 

refers root , searches folder1 there !

i need second address !

to resolve second address root, need add runat attribute follows:

<a href="~/folder1/folder2/1.jpg" runat="server">
