i have web cache enabled and in high traffic hours most of the images are not shown… it´s like a broken link to the images… it happens in images stores in imagehosting sites … is there a logical reason for that?
right-click on the image and click on “view image” (or simply open the path to the image in your browser). what does it show? is it the image, or some error ?
the image is shown
then there is a problem in your browser … upgrade to firefox 
i already have firefox 2…
i will try disabling some of the extensions then
simply try another computer and another browser - is the problem still there? experiment and see what causes this.
