cos the man who edited it make it smaller by resizing it...
ususally when we take a picture by camera, the resolution is big, maybe 1mb at least and around 2-5 mb...
so its big...and of coz the picture will be big if we print it out..so u dont have to enlarge it..
im sorry...but i dont think there is a way...
have u scan the HDD?? if theres no virus i think its not because of the viruses...
u know its not usually viruses attack files..when we scan and detect the virus, the antivirus will delete it and if its attached to files it will delete files...
i always had the same thing too..after i deleted all of the stuff in my pendrive, theres still some used space though...n heres what i do, i formatted it and everything goes back 2 normal..
