They seem to have done away with the bulk uploader, that thing hung up on me so much I quit using it anyway.
They have drag & drop now or if you read the fine print To Bulk Upload, select multiple photos by holding SHIFT or CONTROL as you click(click the Bowse Files button) once you have the file folder open where the photos are located
I see they have a Photbucket Desktop program....bet that's the ticket but I have not tried it
