Hello
I need to use a set of pictures as answer options. I know how to implement it as a trial with inputdevice being a mouse. However, unlike with check boxes or radio buttons, as soon as a picture is clicked, the trial ends and (1) the response of the participant is not seen and (b) the participant can't change the response.
Would be grateful for any ideas or examples of relevant scripts

This is only true if don't take care of allowing (1)  and (2), which can be done like so:

<values>
/ runcount = 0
/ selecteditem = ""
</values>

<block myblock>
/ trials = [1=cat_or_dog; 2=summary]
</block>

<trial cat_or_dog>
/ ontrialbegin = [values.runcount = values.runcount + 1]
/ ontrialend = [if (trial.cat_or_dog.response == "cat") {shape.catbg.color = green; values.selecteditem = "cat"; } else {shape.catbg.color = black}; ]
/ ontrialend = [if (trial.cat_or_dog.response == "dog") {shape.dogbg.color = green; values.selecteditem = "dog"; } else {shape.dogbg.color = black}; ]
/ stimulusframes = [1=catbg, cat, dogbg, dog, submit]
/ inputdevice = mouse
/ validresponse = (cat, dog, submit)
/ isvalidresponse = [if (trial.cat_or_dog.response == "submit" && values.runcount == 1) false else true ]
/ branch = [if (trial.cat_or_dog.response != "submit") trial.cat_or_dog]
/ recorddata = false
</trial>

<trial summary>
/ stimulusframes = [1=yourselection]
/ validresponse = (0)
/ trialduration = 3000
</trial>

<text cat>
/ items = ("Cat.jpg")
/ position = (30%, 50%)
/ size = (20%, 20%)
/ erase = false
</text>

<text dog>
/ items = ("Dog.jpg")
/ position = (70%, 50%)
/ size = (20%, 20%)
/ erase = false
</text>

<shape catbg>
/ shape = rectangle
/ color = black
/ size = (25%, 25%)
/ position = (30%, 50%)
/ erase = false
</shape>

<shape dogbg>
/ shape = rectangle
/ color = black
/ size = (25%, 25%)
/ position = (70%, 50%)
/ erase = false
</shape>

<text submit>
/ items = ("SUBMIT")
/ txbgcolor = grey
/ size = (25%, 10%)
/ position = (50%, 90%)
/ erase = false
</text>

<text yourselection>
/ items = ("You selected the <%values.selecteditem%>.")
/ position = (50%, 75%)
</text>

If you prefer using checkboxes, see this script: https://www.millisecond.com/download/library/v3/selectitems/selectitems.zip
