how to disable caching pictures

[Ufit]

I have image control with jpeg url on my asp.net web. That jpeg has the same name but changes
Problem is that web is caching the old one even if its contents have changed.
I cannot change the name of that pic but I must display current image.
Please help with some good solution. Thanks

I trick the browser by adding a random query parameter to the image url:

'myPicture.jpeg?' + (new Date()).getMilliseconds()

Checked - doesn't work. Any other ideas?
Thanks

It doesn't with other non jpeg pics too but I solved that with other trick.
Anyway other question - how to display
a webform in separate window from main form instance?
F.ex.
Dim f as New WebForm2
WebForm2. ??????
Thanks for help

No - that's WinForms.

You need the Javascript window.open syntax.
