OK, so I have, mixing PvZGW and GTAV into a picture. The problem is that the file's too huge, 4.4 MB to be exact. I want to make this pic for the background picture in PvZFF wiki, but I believe it'll make the page longer to load. Someone here tells me to use something called "pngcrush" but it's some sorta command line program that I dont rly understand.

Can anyone tell me how to do it? If you can, can you also pngcrush my image to make it smaller?
