Hi, I would like to remove the category and subcategory icons so that instead all one would see is a list of text. I found this code here

table.ecwid-productBrowser-subcategories-mainTable img {
display: none;
}

(on this page )
but it doesn't seem to be working. I've tried the other codes such as hide the text but display the icon and it does work so I'm not sure what's wrong there...

Thanks for reading and any help will be greatly appreciated!
