Here's some food for thought:
1 - since TIFF files are about 10x larger than jpegs you can get many more photos on the memory card if you converted them all to jpegs.
2 - also what what I've done is to crop my images to the same size ration as the digital frame. I then resized the images to the same pixel dimensions as the frame. This reduces the file size of the image files gives me the most number of files that I can get on the memory card with no loss of clarity on the frame.
3 - also since the memory card is formatted for PCs, probably MS-DOS (FAT), there is a limited number of files that can be added to the root directory of the card. Therefore, it's best to put the photos in a folder and add the folder to the card. It will sound only as one item in the root director and that way you can fill it up to it's maximum capacity if need be.
