Presumably because of the values references in your /select attributes. The respective <values> are apparently =0. There is no / can be no 'zero-th' item. Set the respective <values> entries to 1.

Define two <counter> or <list> elements, one with 1-10, the other one with 11-18. Sample from the correct counter or list in practive vs. test trials.

Before you move on, I recommend you (a) complete the various tutorials included in the Inquisit documentation and (b) work through the script you are planning to adapt until you fully understand how it works prior to making any modifications.

Is it right to change all the <value> entries to 1? like,

/smo_A1 = 1
/smo_A2 = 1
/smo_A3 = 1
...

I tried, but then only the first picture appears although I set the order randomly..

Thanks,

<picture smoking>
/ items = smokingpics
/ position = (50%,50%)
/ erase = false
/select = values.selectsmo
/ size = (30%, 30%)
</picture>

<picture control>
/ items = controlpics
/ position = (50%,50%)
/ erase = false
/select = values.selectctrl
/ size = (30%, 30%)
</picture>

Those are the two <values> entries you'll probably want to initialize as 1.

Sorry, I don't follow :(  What does it mean to initialize <values> entries as 1?

<values>
[...]
/selectsmo = 1
/selectctrl = 1
[...]
</values>
