This is what I sent him:
To attach them in a post... click POST REPLY, check the embed picture in post box and click the link to upload from your computer. If you are linking them from another site, use the [IMG][/IMG] tags.
For your profile, it's in My Profile, select the option you want, upload it from your computer, scroll down hit APPLY and you should be all set, if you have any trouble with avatars or profile pics, just email it to me and I'll set it up for you.
