I know how to get a picture from my computer but how do I upload it to a post or to my account and/or where do I save it to?:confused:

Thanks

If you're trying to post an avatar then you would:
1. Go to user CP
2. click on "Edit Avatar"
3. click "Browse"
4. look through your pictures and double click on the image you want (please note size)
5. The last step should be "upload photo", or "save", I'm not sure which but it is pretty self-explanatory in there.

For a post:
1. click on New Post
2. scroll to bottom for "Manage Attachments"
3. click "Browse"
4. 4 and 5 from above should be the same.

Hope that helps some.

my signature has disappeared, one minute it was there and next poof gone!! what's happened???

You need to find an image hosting server, such as Photobucket, and upload the pictures to that account. Then place the link between the image tags that suit this forums format:

"URL of desired image" like this.
