You'll want to set up at least one <trial> element that displays the picture for 10 seconds. You'll then want to follow that up by a <surveypage> displaying your 4 <checkboxes> questions. In a nutshell:

<block someblock>
/ trials = [1-10=sequence(showpicture, ratingpage)]
</block>

<trial showpicture>
/ stimulusframes = [1=mypicture]
/ trialduration = 10000
/ validresponse = (0)
</trial>

<picture mypicture>
/ items = myitems
</picture>

<item myitems>
/ 1 = "pic01.jpg"
...
/ 10 = "pic10.jpg"
</item>

<surveypage ratingpage>
/ questions = [1=checkboxes1; 2=checkboxes2; 3=checkboxes3; 4=checkboxes4;]
/ showpagenumbers = false
/ showquestionnumbers = false
</surveypage>

<checkboxes checboxes1>
...
</checkboxes>

<checkboxes checboxes4>

</checkboxes>

Supreme Being, you strike again. Here is the code where I am at and where im stuck...

<expt RatingScales>
/blocks = [1 = DISC]
</expt>

<item DISCimages>
/1 = "A big_circ dotted__.jpg"
/2 = "T big_circ dotted__.jpg"
/3 = "A big_circ solid__.jpg"
/4 = "T big_circ solid__.jpg"
/5 = "A big_squ dotted__.jpg"
/6 = "T big_squ dotted__.jpg"
/7 = "A big_squ solid__.jpg"
/8 = "T big_squ solid__.jpg"
/9 = "A sm_circ dotted__.jpg"
/10 = "T small_circ dotted__.jpg"
/11 = "A sm_circ solid__.jpg"
/12 = "T small_circ solid__.jpg"
/13 = "A sm_squ dotted__.jpg"
/14 = "T small_squ dotted__.jpg"
/15 = "A sm_squ solid__.jpg"
/16 = "T small_squ solid__.jpg"
</item>

<checkboxes DISCRatingScale>
/ caption="Pick one or more of the following choices:"
/ required = true
/ options=("choice1", "choice2", "choice3", "choice4")
</checkboxes>

<surveypage DISCRatingScaleSP>
/questions = [1-10 = DISCRatingScale]
/showpagenumbers = false
/showquestionnumbers = false
</surveypage>

<picture discrimination>
/items = DISCimages
</picture>

<trial picture1>
/stimulusframes = [1 = discrimination]
/trialduration = 1000
/validresponse = (0)
</trial>

<block DISC>
/trials = [1-10 = sequence(picture1, DISCRatingScaleSP)]
</block>

--------
I have 16 possible pictures, I need to pick or set a seqeunce for only 10, no replacements. But it can't be randomized. It must be fixed for each subject.
For now, it can be (1, 3, 5, 7, 9, 16, 14, 12, 10, 8)
Is there a way to set a fixed sequence like in cyberball? 
After, ideally, this would all be one big block, and i would need to run three more blocks. so the entire experiment would run 4 blocks of 10 trials each with a fixed schedule of pictures.

Yes, you can specify fixed sequences. Here's a quick example using <text> elements, it works the same with <picture>s:

<values>
/ itemnumber = 1
</values>

<expt>
/ blocks = [1=ablock; 2=bblock]
</expt>

<block ablock>
/ trials = [1-5=atrial]
</block>

<block bblock>
/ trials = [1-5=btrial]
</block>

<trial atrial>
/ ontrialbegin = [values.itemnumber=list.asequence.nextvalue]
/ stimulusframes = [1=mytext]
/ validresponse = (57)
</trial>

<trial btrial>
/ ontrialbegin = [values.itemnumber=list.bsequence.nextvalue]
/ stimulusframes = [1=mytext]
/ validresponse = (57)
</trial>

<text mytext>
/ items = myitems
/ select = values.itemnumber
</text>

<list asequence>
/ items = (1,3,5,7,9)
/ selectionmode = sequence
</list>

<list bsequence>
/ items = (2,4,6,8,10)
/ selectionmode = sequence
</list>

<item myitems>
/ 1 = "A"
/ 2 = "B"
/ 3 = "C"
/ 4 = "D"
/ 5 = "E"
/ 6 = "F"
/ 7 = "G"
/ 8 = "H"
/ 9 = "I"
/ 10 = "J"
</item>
