Is there a way to select certain items from the items list in the picture element on Inquisit? I am trying to create an experiment to show sequences of four items in a fixed order. 

For example, if I have:
<item stims>
/1="1a.jpg"
/2="1b.jpg"
/3="1c.jpg"
/4="1d.jpg"
/5="2a.jpg"
/6="2b.jpg"
/7="2c.jpg"
/8="2d.jpg"
/9="3a.jpg"
/10="3b.jpg"
/11="3c.jpg"
/12="3d.jpg"
</item>

<item probestims>
/1="1a.jpg"
/2="2b.jpg"
/3="3c.jpg"
</item>

Is it possible to do something like-

<picture enc1>
/ items = item.stims (1,2,3,4) ## to present the first four items
/ size = (parameters.stimsize, parameters.stimsize)
/ select = sequence
/ position =(50%, 50%)
</picture>

<picture enc2>
/ items = item.stims (5,6,7,8) ## to present the next four items
/ size = (parameters.stimsize, parameters.stimsize)
/ select = sequence
/ position =(50%, 50%)
</picture>

<picture enc3>
/ items = item.stims (9,10,11,12) ## to present the next four items
/ size = (parameters.stimsize, parameters.stimsize)
/ select = sequence
/ position =(50%, 50%)
</picture>

<picture probe1>
/ items = item.probestims (1)
/ size = (parameters.stimsize, parameters.stimsize)
/ position =(50%, 50%)
</picture>

<picture probe2>
/ items = item.probestims (2)
/ size = (parameters.stimsize, parameters.stimsize)
/ position =(50%, 50%)
</picture>

<picture probe3>
/ items = item.probestims (3)
/ size = (parameters.stimsize, parameters.stimsize)
/ position =(50%, 50%)
</picture>

And then

<item fixationcross>
/1="fixation.png"
</item>

<picture fixation>
/ items = item.fixationcross
/ position = (50%, 50%)
/ size = (20%,20%)
/ valign = center
/ halign = center
</picture>

<text pnp>
/ items = ("Was this item present in the sequence?")
/ position = (50%, 10%)
/ fontstyle = ("Arial", 5%, false, false, false, false, 5, 1)
/ size = (25%, 10%)
/ txcolor = black
/ txbgcolor = #afafaf

Yes, you do this via the /select attribute.

I.e.

<picture enc1>
/ items = item.stims
/ size = (parameters.stimsize, parameters.stimsize)
/ select = sequence(1,2,3,4)
/ position =(50%, 50%)
</picture>

<picture enc2>
/ items = item.stims
/ size = (parameters.stimsize, parameters.stimsize)
/ select = sequence(5,6,7,8)
/ position =(50%, 50%)
</picture>

<picture enc3>
/ items = item.stims
/ size = (parameters.stimsize, parameters.stimsize)
/ select = sequence(9,10,11,12)
/ position =(50%, 50%)
</picture>

<picture probe1>
/ items = item.probestims
/ size = (parameters.stimsize, parameters.stimsize)
/ position =(50%, 50%)
/ select = 1
</picture>

<picture probe2>
/ items = item.probestims
/ size = (parameters.stimsize, parameters.stimsize)
/ position =(50%, 50%)
/ select = 2
</picture>

<picture probe3>
/ items = item.probestims
/ size = (parameters.stimsize, parameters.stimsize)
/ position =(50%, 50%)
/ select = 3
</picture>
