Report images change based on company name

Using different images  according to selection of company

here i am using  two images 

you can see two images in the picture

right click on the image and select   the image  properties and  click on the visibility tab 

now click on the expression  box and enter the  expression 

eg:=IIF(First(Fields!ItemId.Value, "student")="1101",False, True)

 after adding expression in one image now  repeat the same step  for another image 
but the  condition differs ( you can see the condition in below pic)

Report generated is based on  my condition  parameter  itemid= 1003
