First of all, turn your email on in your profile as you have it disabled. You must have your email turned on to sell here in the EE.
Secondly, when you go to the page in Photobucket where you see your pics, there will be 3 links under each pic. All you have to do is copy and paste the bottom link into your ad to have your pics show up.
And last but not least, do not bump your ads with replies before 72 hours to avoid having your ad locked or removed.
Good luck with your sale.
