Dynamic Pictures together with HTML

[Anon]

Following prob:
I have a php-script and load some data from the database. Now I want to implement a graphic showing the data as a combined line-/bar-diagram.
This works fine with one problem:
I get the data, create the image and store it on the disk with a fixed filename.
The next line in the script I get the just stored image and show it with an IMG-tag.
The problem is (I assume due to cache) that I always get the picture created one step before. If I reload the page manually I get the correct picture. So, first thought was to reload the page every time automatically, but this isn't a good solution.
The better way would be to force the browser to ignore the cache and to load the page entirely from the server.
But how does it work???

Has anyone a good idea how I can include the dynamically created picture into the script without storing it on the disk???

Thanks in advance.

You could add a unique number to the url of the page. that way the cache will think its a new date each time. Something like

main.html?uid=2075938459347

it doesnt matter what the number is. I use date and time to generate a number that way I wont get duplicates.
