To do this, you need to employ a bit of trickery. One way is to have a <picture> element displayed of-screen on the <surveypage>, with the <image> element referencing that <picture>'s current item:
<block myblock> / trials = [1-5=Explicit1] </block>
<item valence> /1 = "prime_lit1.jpg" /2 = "prime_lit2.jpg" /3 = "prime_lit3.jpg" /4 = "prime_lit4.jpg" /5 = "prime_lit5.jpg" </item>
<picture valpic> / items = valence / position = (-20%,-20%) </picture>
<image val> /items = ("<%picture.valpic.currentitem%>") /position = (6.25%,2%) </image>
<slider slid_val> / fontstyle = ("Arial", 4%) / position = (14%, 75%) / labels = ("Negative", "Positive") / range = (1,9) / slidersize = (60%, 6%) / showtooltips = false / required = true </slider>
<surveypage Explicit1> / stimulusframes = [1=valpic] / fontstyle = ("Arial", 3%, false, true) / questions=[1=val;2=slid_val] / showpagenumbers = false / showquestionnumbers = false / finishlabel = "Next" / nextbuttonposition = (60%, 90%) </surveypage>
