Show image depend on parameter [message #262588]

Hi! How can I show an image (logo) from specific location depend of
parameter selected? We have a few different companies using the same
report and depend on the company code they enter as a parameter they need
to see their logo. We dont have any info about images in database. Ive
tried to use URI, but it doesnt like any type of expression apart from
the straight path to the image. Can you PLEASE point me to the right
direction??
Thank you

Natasha,

There are a couple of different ways to do this. The easiest way is
probably to add a bit of script into the images onRender event to change
either the URL or the embedded image name based on the value of that
parameter. Below is a snippet from the onRender method to change which
embedded image of a report is used based on the value of a parameter.

if (params["NewParameter"] == 1)
{
this.setImageName("classicCarsLogo.jpg");
}
else
{
this.setImageName("unitTests.jpg");
}

Thank you!
i need to show relative path, sort of "../../images/companylogo2.jpg"
which doesn't work for some reason...
also, i need this image as logo on Master page. what do i need to do when
i place logo? if i choose image URI, showld i shoul path to one of the
image and script will change it to another image?

Thank you!!

Natasha,

The same logic applies. Instead of using setImageName, you can use the
setImageURI method. It should work in the Master Page as well. Let me
see about putting together a tutorial on how to do this since I already
have the example sitting here.
