Camera Connection Kit Problem

I have a new iPad 2 and am really enjoying the iPad experience. However, I am having a problem importing “JPG” pictures from the SD Card reader purchased with the “Camera Connection Kit”. The pictures work OK on the SD Card interfaced to my PC. I am following the instructions exactly as explained (Lock the iPad, insert the SD Card Reader, insert the SD Card in the Card Reader, Unlock the iPad). Nothing happens on the iPad (it just opens to the home screen). I have saved some photos from e-mails and with the Sony Cybershot interfaced directly to the USB Adapter that comes with the “Camera Connection Kit”. Further, I can view those photos. However I cannot successfully import photos via the SD Card Reader. I visited an Apple Retail Store and had them check it out. My SD Card reader purchased with the “Camera Connection Kit” worked with their SD Flash card, but not with my two. I had them format my SD card and import one of their photos to it so I could try that particular SD Card in my SD card reader. No luck with my iPad 2. They suggested I purchase a new SD Flash Card. I did. I purchased 2 Sony SD Cards and have the same results (do not work). Question, has any one else experienced this? Does any one have any suggestions? Is there a particular MFG SD Flash card that needs to be used? Or, perhaps, the SD Flash card need to be formatted a special way?
By the way, I have two calls into the Apple Support Line and have been waiting for a call back for 10 days. Thanks, Richard

You are Correct

Thank you. You both are correct. The SD Card needs to have a Folder named DCIM and in my case a second folder inside named “101MSDCF” (which contain the photos). This is just the way it is inside the camera flash card on the Sony Camera. Then the photos do import correctly. Thank you for your assistance.
