Some of my images dont display

[Jimster_s]

ive installed the software from fresh, set it all up and some of the standard buttons dont display. one example is the button_reviews.gif. this is found in

catalog/includes/languages/english/images/buttons/button_reviews.gif

 

when you click on a product the review button is missing, if i right click on it and select view image i get this error

i have chmod the images directory and the buttons directory to 777 to see if this would make a difference and it doesnt. if i need to have them set to a chmod value can you let me know what it is.

 

there are plenty of other buttons too like the english flag in the language box,

the continue shopping button: button_continue_shopping.gif

etc etc

 

they are all there on the web but for some reason you cant access them in the cart or even by putting the direct line to them in the browser

 

other images like the images of the products work fine

 

 

any help
