modifying uploaded file

i am using single file upload and it works fine except:

when i modify record and replace image, the modify success screen still shows old image. if i click refresh button on my browser, the image is replaced with the new one. so i guess the browser is grabbing the old one from the cache instead of getting new image from record.

is there a way to force the display to the new image? thanks

i thought i had fixed this long ago but cannot find the answer. i have searched forum and faq and cannot find solution. can anyone help please?

I've seen references to using meta tags that mention something along the lines of "no-cache", but I don't know how accurate or html-ly correct it is..
