This might be a bit of a simple question, but all my searches are bringing up Acrobat answers.

Is it possible (and if so, how) to use a check box to hide and/or show an image field?

In the end I'll need the various check-boxes to hide not only specific image fields, but also multiple text fields. Checkbox options were not a problem in Acrobat (in fact were very simple) but Acrobat lacks the ability to add image fields. However if I'm totally wrong and via some method other than, oh lets say black magic, I can start shoving image fields into Acrobat that would circumvent the checkbox problem I'm having with Livecycle.

LiveCycle ES 8.2
Acrobat 9 Pro

I don't know if this will help, but I had the same problem with LC a while back. First I had to save the document as "Dynamic" instead of "Static". The code was something like this:
Set this.presence="hidden" using Javascript in the docready for all fields you want to hide when the pdf loads.
Then in the change event for the Checkbox using FormCalc use something like this:

if ($.rawValue == 1) then
Image.presence = "visible"
TextField1.presence="visible"
TextField2.presence="hidden"
TextField3.presence="visible"
else
Image.presence = "hidden"
TextField1.presence="hidden"
TextField2.presence="visible"
TextField3.presence="hidden"
endif

In my test form i have three text fields, a checkbox and an Image Field. When the form loads only the checkbox and TextField2 are visible. When the box is checked, the image and TextFields 1 and 3 appear.

Actually, Acrobat (AcroForm) does have an image field, the button. Buttons can show images and be setup to load an image dynamically. They can even submit an image just like it was data.

But if you'd like to use the dynamic features on a LiveCycle form I'd suggest you watch this video.
