I m a student .Want to make a project on virtex 5 mainly XC5LX110T.
My job is to read image file and then the contents of image like RED GREEN AND BLUE values of image to be loaded in block rams of virtex 5 fpga kit and another block ram for storing another variable tmeperature of size same as R G B arrays.
Xilinx have mentioned that XC5LX110T has internal RAM memory of 5328Kb so what size of image will I have to use to ensure that I use internal DDR RAM.
And how to load all values of RGB in the block ram???

You are basically asking how to design what you have described, is this correct?
What experience with FPGA design do you have?
Your first step is to define the requirements of your design, including the size of the image you wish to store. Do you have such a design definition?
Your next step is to transform your design definition to a block diagram. Do you have a block diagram for your new design?
Then you need to describe each block in your design with more detail -- enough detail to clearly describe your Verilog or VHDL implementation code.
Finally, you translate the detailed design description, block by clock, into HDL code.

My image is 24bits/pixel i.e colour image .
I want to store each element of image i.e R G and B colour values in internal RAM.
So in all I need four block ram (one extra for storing Temp array) of size say 100 by 100 pixels
whats d way i do it?????

"Please guide me on this."
Design and test is small stages.
Do an LED-blinking design FIRST OF ALL to get confidence with the tools. Then proceed with your design in stages.
For instance, get the PC -> FPGA communications up next.
Does the PC need some return value back from the FPGA to indicate that the FPGA has received data?
How does the FPGA know when it has got all the data it needs?
