Are you wanting the "GoatProducts" heading to replace the "Categories" sidebox heading? Then you want to use the Image Titles mod for that and the other box headings.

I notice that you have some text constant names displaying where there is usually some ordinary text, like TABLE_HEADING_IMAGE, TABLE_HEADING_PRICE and TEXT_NO_PRODUCTS. Did you delete those define statements in an attempt to eliminate the text? That won't work - you need to restore the define statements and change the definitions from 'Whatever text' to '' (two single quotes).
