Hiding/unhiding a report field by mouse click

How would you go about making one of your fields hidden until you click on it?right click the textbox and go to properties, go to the visibility tab. Check hidden and check "can be toggled by another item". The Item selected will have a + or - on it, or you can set an expression to control visibility otherwise. If this is not what you're looking for, please provide more information about the report, mainly type of report (matrix, tabular).|||Its a matrix report, and the specific field is a picture. What I want to do is have the report run without displaying the picture, but if you click on the box the picture will then display. So I want it to default as hidden and then have some sort of button or check box to display the image.|||I have never used an image control but if there is a visiblity tab in the properties you could have it controlled by an arbitrary textbox placed perhaps in the corner of the matrix that says "Show Picture". When you set the visibility control property of the image to a textbox, the textbox will automatically show the plus or minus signs.
