How many pictures do you see in your Revel account? I looked up your account info as I did see a Total Count: 882 that was migrated from your Photoshop.com to Revel.
Which version of Elements are you using? Can you provide details of how many images that you are trying to upload and how many are showing up? How are you trying to upload the images? Have you tried to log into Adoberevel.com and upload pictures to see if they show up?
Please see our FAQ Forum post "How do I upload photos to Revel" http://forums.adobe.com/message/5114160#5114160 as there are screen shots to show you the different ways to upload to Revel.
