Well my problem is that i cant use large resolution pictures and i have to keep all pictures at 440 px width. What i need is when you are on the detail page of a picture to have the possibility to click on the picture to see its full size.
This means that you need to have 2 thumbnails + one small and one in detail page.
If there is someone that knows how can i do that or other things that helps me to have the big picture in a new window, PLEASE help me !
