Images are smaller when viewed into Phoca Gallery

[Yabuki]

Hello everybody,
after uploading images, when I view them into Phoca Gallery those are constantly resized into small ones, I'm uploading 640x480 pictures and I would like them to keep this dimension, can somebody please explain to me how to do it and what I'm doing wrong?

Thanks in advance

This is because PhocaGallery resizes them for you. Check the documentation.
If you have any questions after you tried playing around with the parameters, feel free to post them here.
