Well I,ve deleted cookies but all its done is ruin my favourites list lol and I still cant see my avatar. Why? It was perfectly ok until today. God knows why, I give up. I shall end up throwing my pc out of the window soon.
The issue isn't with your cookies, it's with your browser cache or your ISP. If you empty your temporary Internet files (or browser cache), it will delete all of the images it has been storing up so that instead of having the site resend you picture files you already have, it will just load them off your computer. Unfortunately, if a picture changes, it can sometimes take days before your browser will actually notice something has changed and transfer the new one. Sometimes you can bypass this by refreshing the browser page, but not always.
Some ISPs keep copies of our content cached on their own computers, and this can be aggravating because sometimes you won't see new messages or changes as quickly as others will. There is nothing you can really do about this unless you change Internet providers.
I'd start by emptying your browser cache (not your cookies or favorites) and then refresh the page and see if that works.
