I have a question.

I am using highchars in my project and i wanna know if it's possible to show an image (in this case i wanna show a google map static image) on the tooltip?

You can Use HTML to render the contents of the tooltip instead of SVG. Using HTML allows advanced formatting like tables and images in the tooltip.

Check out the 'formatter' option inside tooltip:

$(function () {
    var chart = new Highcharts.Chart({

        chart: {
            renderTo: 'container'
        },

        xAxis: {
            categories: ['Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun', 'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec']
        },

        tooltip: {
            useHTML: true,
            headerFormat: '<small>{point.key}</small><table>',
            pointFormat: '<tr><td style="color: {series.color}">{series.name}: </td>' +
            '<td style="text-align: right"><b>{point.y} EUR</b></td></tr>',
            footerFormat: '</table>',
            formatter: function() {
                return '<img src="http://static.adzerk.net/Advertisers/bd294ce7ff4c43b6aad4aa4169fb819b.jpg" title="" alt="" border="0" height="250" width="220">';
            },
            valueDecimals: 2
        },

        series: [{
            name: 'Short',
            data: [29.9, 71.5, 106.4, 129.2, 144.0, 176.0, 135.6, 148.5, 216.4, 194.1, 95.6, 54.4]
        }, {
            name: 'Long named series',
            data: [129.9, 171.5, 106.4, 129.2, 144.0, 176.0, 135.6, 148.5, 216.4, 194.1, 195.6, 154.4].reverse()
        }]

    });
});​

You can just insert the code of the static Google map image you were talking about.

Hope that helps.
