pnAvatar uploads the file as 644 permissions to the server, and then subsequently cannot upload another to replace any that have been uploaded. Is this a pnavatar issue? php running as limited user issue? httpd issue? Anyone help? Thanks.

In fact, module says that avatar was uploaded successfully, yet does not change - old one still there.

Nevermind - it is working...but as its named the same, the browser cache shows the old one until refreshed.

Perhaps a javascript refresh should be added if uploaded over an existing one? Or is there a better way to signal a browser not to cache an image?
