can i load and use in runtime unity game ?

first ,Hi and pardon me for bad English writing!

i want to browse a picture form my hard disk and use it (e.g for texture of an object) when my game is running, then save it in assets. can anyone help me ?

You can use WWW class and load png files from local. see WWW.texture() . but Instead of "http://" for local files write "file://". For example : "file://c:/test.png "

tnx AliAzin ,that's pretty work, but i have another simple problem , when a picture is loaded i want to save and use it anytime we run the game , can i save this picture somewhere in assets folder?

i most have a data base for saving many information in project , i can save the url & obj in db then every time the game is running, read db and load picture but realy i dont know this is true way
