PicLens module - problem to customize logo

hi everybody,

i'm writing you from france because of a problem with piclens module. first i have write somewhere in the forum but i'm not sure that was in the good place so i'm posting here.

as you can see here http://www.fleury-nous-rassemble.fr/?q=image/tid/1 , when you click on "Start Slideshow", there is a broken picture in the top of the window.

i have try to change it in the website setup -> PicLens -> Logo [You can add a custom logo to your slideshow. You may use any image (PNG, JPG, or GIF). A 26-pixel high logo will fit nicely into the top bar. By default, the shortcut icon is used, configured at admin/build/themes. You can override it underneath by entering the path to a custom logo.] but there is no button to validate it and nothing change if i press enter.

i've seen some examples here:
- http://menlotravel.com/ with an icon
- http://emilysphotosite.com/ with text

i would like to be abble to change the broken picture by a nice logo or some words on my website but i don't know where to do it.

i haven't found anything about piclens in the style.css or in the settings.php.

looking in the log files of drupal, i'm discovering that there is an error back each time i try to see the gallery:

but the file /www/misc/favicon.ico exists, i have also try to change my drupal's theme favicon by a .png or .gif but nothing better. it's not the logo i would like to see but maybe there is a link between that and what i would like to do in the first post.

someone could help me? it should be very very very nice.

thanks a lot in advance, camille
