Digital Photo Frame and memory cards

Digital Photo Frames:

I am having trouble loading pictures to my memory card. When I drag and drop a picture to the memory card, the computer tells me that it can not be copied because a directory or folder can not be created at this location. I have a 512MB card, I have 43MB of pictures on it and all of a sudden the above happens. I need help, cause I can not figure out what to do or what I am doing wrong. HELP

Most likely the files were not copied into your computer right. You need to reupload them I'm thinking.
