Vhdl code to read/ write from sram

Ok ok, sorry for not explaining that,

Where do you want to image? Whats the purpose of the project?

I have image on my PC and I want to show it on the VGA ( since my project is to add a watermark and show the image, however now I just want to show the original Image)

Cant you just load it via an RS232 link?

I need to save the image on SDRAM to read it and modify it in future. furthermore I didn't use RS232 before

Why do you need Nios?

I think I need the NIOS for using the SDRAM , that's what I read.

what examples are you talking about?

Examples are the templates like hello words no one worked with me in Eclipse

What VHDL have you got? I didn't understand but I am using VHDL editor in Quartus II 13.

Hopefully I answered now :(
