How to store different formats of images into the internal flash of micro controller

Thank you for your reply.

Do you have any sample code related to storing raw images(if the image file is of .jpeg or .hzk it would be more helpful) and sending them to LCD through UART.

No.

All you need to do is read in the file and send it byte at a time via the UART. Of course, you might want to include headers, envelopes, checksums etc. to detect error situations.

You'd have to unpack JPEG images to get data you could display.

There should be many resources on the web describing imaging formats.

Standard methods for storing "data" in memory can be applied here. You could create linkable objects, or express the data as a "C" array that the compiler can build. You could also create a file system to manage multiple data objects in large NAND images, etc.
