Verilog to switch pictures for VGA display

vga tutorial verilog

Hi, I need help designing a circuit with Verilog to output a picture onto the screen. I know how to do this with one picture, but I don't know how to do it with multiple pictures.

The objective is to show a picture at a time, which is switched according to user input.

I think I could do the FSM but I'm getting frustrated since I cannot use output from different .mif files. Could someone please provide me a tutorial on this, and explain lpr_ram_dq? I don't know whether I'm supposed to implement it, and how I could use it for my VGA display switcher implementation.

Thanks in advance.

One way would be to have only one '.mif'-file that included N images to be loaded into one RAM of Nx(image_size) bytes in length.
The starting-address of the display-routine could then be changed to cause different images to be displayed.
Good form would have the starting-address changes to take place in the vertical retrace interval.
