Not sure how to get it turned back on for you. As for uploading pics you need a picture hosting site. I use www.tinypic.com
because I don't have to have an account. I save all my uploaded picture forum codes in a word document on my computer for later usage. Go to http://www.tinypic.com
click on browse, select your pic from your computer/phone/ipad. Under resize select message board for pics on here (use thumbnail for signatures and avatar for the little avatar pics). then click upload now. Enter in the correct anti-spammer code and wait. When the codes pop up copy and paste the forum codes here.
