When you double click on your picture do you have a photo editor that pops up -- something standard like Microsoft Office Picture Manager? Cause you can resize pics within these editors. That way you dont have to upload to photobucket first.
Else - yes usually you will have to download back to your pc at new size and then upload to daylily auction.
Also I dont want any more kids -- but a daylily fan is nice -- LOL!!!
(just kidding!!!)
