wiki [[Image(URL)]], the URL address is truncated to its 74 first characters.

[fermaf@…]

I'm trying to publish a wiki page in my trac using a the Image Macro.
When I post an image like this:

[[Image(http://www.lacasadelaposada.com/casa91.jpg)]]

There is no problem and the image is displayed correctly in the browser and when I focus on the image the URL context information (left botton corner is shown correctly).

But when I use a longest URL address like this:

[[Image(http://chart.apis.google.com/chart?cht=bvs&chs=500x200&chco=00FF00,FF0000&chdl=OnTime|TimeOut&chd=t:0,0,0,1,0,1,0,0,0,1,0,0|0,0,0,3,0,0,0,0,1,0,4,2&chds=0,5&chbh=25&chtt=Evoluci%C3%B3n+de+Tickets+Cerrados(Fixed)|Prioridad:%22Normal%22|Semanalmente+2009&chxt=x,y,x,y&chxl=0:|1|2|3|4|5|6|7|8|9|10|11|12|1:||1|2|3|4|5|2:|||Semanas+del+2009||||||(%C3%BAltima%20es%20del16+al+22+de+marzo)|3:|||||Cantidad)]]

The image is not displayed and the context information in my browser (left botton corner) only shows a truncated URL when I am on the place where should be the image. The url displayed has a length 74 characters. like this:

http://chart.apis.google.com/chart?cht=bvs&chs=500x200&chco=00FF00,FF0000

I have test it using Firefox, Explorer and Opera and the same problem.
