Q: I transferred some pictures from PC to SDHC card but they are Jpeg can I transfer them to my IPad?

Yes - but you will need the camera connection kit

Yes, you can use the camera connection Kit{s Sd card reader, but the images must be in a folder called DCIM and they must have filenames that are exactly 8 characters long plus the 3 letter extension. i.e. image004.jpg
