image changed but not reflected in the control

[t4nu]

Hi,
I have an image control and let the user to change it.
Any image file uploaded to change the image will be rename to the ID of the user, if the old one is exists it will deleted first.
The problem is, the image is still reflected the old one and not the new one, even after I issue the refresh.
Anyway to force the browser to reflect the changes immediately?
Thanks in advance for the help.

Here's an answer from stackoverflow (very good source of technical information) http://stackoverflow.com/questions/1431 ... oad-images.

They suggest appending a querystring with a random number (or time, or version number, etc.):

Code: Select all

<img src="image.png?80172489074" alt="a cool image" />
