Hi Oliver, I try to send a variable like this

in the recenterInput.tpl I have

<input type="text" name="variableimg" value="" />

the makeSearch function return the dir of the image

protected function makeSearch($searchString) {
   return $row->imagen;

and filterPostRequest set the result into the field

public function filterPostRequest(FilterRequestModifier $request) {
    $searchString = $request->getValue('variableimg');
    if (!empty($searchString)) {

        // To simplify we assume that only one result is returned by the search
        $variableImg = $this->makeSearch($searchString);
        $request->setValue('variableimg', $variableImg);

But don't show the name of the image, now, I try to show an image like this


<input type="image" name="varImagen" id="varImagen" src="{$varImagen_path}"
      style="width:{$varImagen_width}px;height:{$varImagen_height}px;" />

I try to use

protected function drawUserForm() {
    $smarty = new Smarty_Plugin($this->getCartoclient(), $this);
    return $smarty->fetch('varImagen.tpl');

public function renderForm(Smarty $template) {

And the folder images is in htdocs folder, I have the idea how to make my
plugin, but don't understand very well how work it. Thanks for your help.

Thanks and regards,
