did you increase the width and nothing happens? then the problem is that you have the old version of the helpers.php file. download the new one here:
http://www.joomlamusicsolutions.com/downloads/doc_details/34-file-to-fix-images-not-being-shown-on-random-album-module-version-15.html?lang=en

tell me if it works

the helper.php is for those who did upgrade from version 1 to 1.5 as you describe on the download page

"The images on the new Random and Featured albums (and other places in the component) is not showing up on Music Collection being updated from 1.0.2 to 1.5.0"

I install direct version 1.5

Please check this

at the button of the page you will see the random module, the pics showing is samll around 100px, not like the one you have in this site

Regards

because there's a paramter on the module.. called thumbnail width... you can adjust it

take a look my friend...

HI
I tried the width, it just make the width on the pics inside the module wider, not the module itself.

and also how about the height?, how can I change the height?

ah ok, you meant that.

you have to change the width of the module on the skin css file

/modules/mod_muscol_featured_albums/tmpl/jcarousel/skins/tango/skin.css
