i have created a website where the user is able to upload images and then they are displayed on and email which is then sent out to the people of there choice.
the problem i am getting is that the images are being cached and then the new images are not displaying.
i have used if file exist to display the images on the email and also used it to unlink the files once they have been used. When the user comes to use the system next time if they upload an image of the same file type then it is displaying the cached version and not the new image. if a image with a different file type is uploaded then it works, but this will only show different images as long as the file type has not been used.
i have tried using this
<META HTTP-EQUIV="Pragma" CONTENT="no-cache"> <META HTTP-EQUIV="Cache-Control" CONTENT="no-cache">
which has had no effect on the situation. i put the above code inside the head tag is this the correct place to put it. the reason i put it there is because this is usually were the meta tags are placed.
