"Database" image not refreshed
Posted: Thu Apr 11, 2013 2:03 pm
I'm using an ODBC connection to an Excel file to get a list of images to display.
And it's working quite well... my Excel file contains only one column with the full path of the images. I use that value in the "Image path" field of one image object on a page.
My excel file is like this:
FullPath
D:\Slide01.png
D:\Slide02.png
D:\Slide03.png
D:\Slide04.png
D:\Slide05.png
D:\Weather.png
The "Weather.png" is overwritten on the server by a new version every hour (because the weather is changing!). However, it does not trigger any change on the LCD screen... Always displaying the "old" Weather.png. Like if it was taken from a cache or something... Can you help ?
Thanks!
