refresh a cached texture?

Hi All,

Building a ugc gallery where the players have 3 images they can create or edit, these images are saved to server via php eg Bob_1, Bob_2, Bob_3, if Bob then opens say Bob_2.png and changes his image and saves it to server over old Bob_2.png, then I reload it into the webplayer... its the old cached image :( If I clear cache in browser and reopen webplayer the new image is there...

hmmm, I tried adding a random string to the url but still no cigar

eg.

public class example : MonoBehaviour { public string url = "http://images.earthcam.com/ec_metros/ourcams/fridays.jpg"; IEnumerator Start() { WWW www = new WWW(url); yield return www; renderer.material.mainTexture = www.texture; } }

Any pointers appreciated Thanks
