I want to thank you Tricky for your patience, so what do you mean by "without re-compiling the system"? One observation is that I should be able to load different sets of data (different photos, same resolution, same characteristics), so I guess you mean that, I wish to be able to analyze different set of datas.
That method that you mention, how to do this? any specific tool to use? wouldn't be that a Qsys sytem also? Is the ARM play any part on this?

This all depends on what you're doing. Assuming you're using purely FPGA approach, you need to get data into it somehow. The quickest but probably "dirtiest" is to have a ROM in your design initialised with all the values you need - but obviously you're limited to the data in the rom and changing that data requires re-compiling the design.
The better (and only real useful method) is to connect it via some connection so that data can be sent to the design somehow. This may be directly via a UART, PCIe, Ethernet etc. Or via some shared ram space if you're part of some SoC system.
