Hi Jian,

In principle, you could use widget.setPropertyValue(prop_id, value, true); to force update the image, but I found that the image figure will not update the image if the new path is same as old path, so it won't work. I will remove that line to make it work in next version. Right now, you can only refresh the image in a script/rule with a hack by taking use of the workspace file path and local file path, which actually point to the same image file (the trigger pv can be something like sim://ramp): 

importPackage(Packages.org.csstudio.opibuilder.scriptUtil);

var v = PVUtil.getDouble(pvs[0]);

if(v%2==0)
	widget.setPropertyValue(
	"image_file", "/BOY Examples/pictures/valve_on.gif"); 
else
	widget.setPropertyValue(
	"image_file", "C:/Users/Work/java test/BOY Examples/pictures/valve_on.gif");

Thanks,
Xihui

Subject: Issues on image displaying in CSS [SEC=UNCLASSIFIED]

Hi,
We are currently using CSS as a monitor and display for our accelerator running status. We have got some trouble to make image  displayed be refreshable when source file contains has been changed.
For example, if we display an image file from /home2epics/operatorImage/display.png on CSS, however the contains in image file "display.png" is frequently updated (same file name and same location). We are expecting such image changing can be refreshed on CSS. Unfortunately, we cannot find such option in CSS package. 
By the way, similar function in EDM can be refreshed depending upon user's setting such as 1 second or 2 seconds.
Could anyone help us to fix this issue?
Thanks in advance!
Best regards,

Jian
