Working on the next release of AjaxSerach (1.9.0), I have modified the parser to add the following modifiers.
May be these new modifiers could be added to the official Phx plugin. Hereafter is the extract of the ajaxSearch 1.9.0 readme file.

==== new modifiers for the ajaxSearch Phx parser

    to include images in your templates, uses the possible following phx modifiers:

    imgwidth  : image width       -   e.g: <img src="[+as.imageArticle+]" width="[+as.imageArticle:imgwidth+]" />
        provide the image width

    imgheigth : image heigth      -   e.g: <img src="[+as.imageArticle+]" heigth="[+as.imageArticle:imgheigth+]" />
        provide the image height

    imgattr   : image attributs   -   e.g: <img src="[+as.imageArticle+]" [+as.imageArticle:imgattr+] />
        provide the image attributes as height="xxx" width="yyy"

    imgmaxwidth=`length`  : image max width  -   e.g: <img src="[+as.articleImage+]" width="[+as.articleImage:imgmaxwidth=`60`+]" />
        limit the width of the image to a maximum. Under this limit, keep the true width

    imgmaxheight=`length` : image max height -   e.g: <img src="[+as.articleImage+]" height="[+as.articleImage:imgmaxheight=`100`+]" />
        limit the height of the image to a maximum. Under this limit, keep the true height

    These modifiers are particularly usefull with the ajax mode to help html to determine the height of the AjaxSearch pop-up window

These modifiers could be added by changing the parser class as follow:

                    case "imgwidth": list($width, $height, $type, $attr) = getimagesize($output); $output = $width; break;
                    case "imgheight": list($width, $height, $type, $attr) = getimagesize($output); $output = $height; break;
                    case "imgattr": list($width, $height, $type, $attr) = getimagesize($output); $output = $attr; break;
                    case "imgmaxwidth":
                        list($width, $height, $type, $attr) = getimagesize($output);
                        $output = ($width < intval($modifier_value[$i])) ? $width : intval($modifier_value[$i]);
                        break;
                    case "imgmaxheight":
                        list($width, $height, $type, $attr) = getimagesize($output);
                        $output = ($height < intval($modifier_value[$i])) ? $height : intval($modifier_value[$i]);
                        break;

Tested and guarantee wink

Hi, I was having a problem with this script.

I was using a template for a Ditto call ([+paginaAfbeelding+] is a TV with an image-url)

[+phx:if=`[+paginaAfbeelding+]`:ne=``:then=`
	<div class="samenvatting_afbeelding" style="width: [+paginaAfbeelding:imgmaxwidth=`175`+]px;">
		<a href="[~[+id+]~]"><img src="[+paginaAfbeelding+]" border="0" width="[+paginaAfbeelding:imgmaxwidth=`175`+]" title="lees verder..."></a>
	</div>
`+]

Problem was, even though I had a phx statement to check if the TV was empty, the getimagesize() function would get called no matter what.... and I would get a MODx error, stating that this function getimagesize() cannot be empty....

I changed the code in the first post to this (just showing one case...)

case "imgmaxwidth":
if($output != ’’){list($width, $height, $type, $attr) = getimagesize($output);
$output = ($width < intval($modifier_value[$i])) ? $width : intval($modifier_value[$i]);}
break;

Which solved my problem

You guys probably have better If statements (!$output) or something, but I’m on a basic level php... so change it if you want....
Glad I solved it myself, cause I was going crazy!

still having some problems with spaces in folder names with the %20.... but gonna try to fix that myself too...
