| | I've got a script that generates a graph by creating it as a .png file (I can't output the image directly to the browser because of the way I need to generate the data).
This all works ok however, in order to keep the data managable I've set a limit so that it only displays 12 months data at a time. The problem I have is that when I click on the next button to display the next set of data, the graph remains the same until you refresh the browser.
I've tried using unlink() to delete the image file forcing the script to re-generate it when the script is reloaded but it doesn't seem to delete the file.
The code is fairly lengthy so haven't displayed it here.
Any suggestions? |

Securing Images
- (2)
Just wondering if anyone's worked with securing images to avoid direct linking than just by
obscuring the URL or using a .htaccess file. I briefly looked through the documentation and source
for gallery and it looks like the images are stored under the web root, so anyone with a direct link
can browse the images regardless of user privileges. I was thinking one way of doing this would be
too store the images above the webroot directory so that visitor's can't navigate to them
and having a php script that can read the image dir output the images by sending th...
