when interfacing an LCD and using SDRAM as framebuffer, how to store pictures in the embedded system?

I want to use an SD card on which the picture data is stored. What is the most efficient way to read the picture data? Should I first buffer the data over the SD/MMC DMA in SDRAM and then work with this data or is it easier to work directly with this data from SD card?

What is the best way?

Does anybody have some experience and can help me? :-)
