根据你提供的代码，你可以尝试以下方式来修改判断条件：
<image v-show="getThemeNum() === 1" src="https://img.forca-world.com/20240626171735346.png" class="cart-img" @tap="openCartPopup"></image>
<image v-show="getThemeNum() === 2" src="https://img.forca-world.com/20240626171735606.png" class="cart-img" @tap="openCartPopup"></image>
<image v-show="getThemeNum() === 3" src="https://img.forca-world.com/20240626171735802.png" class="cart-img" @tap="openCartPopup"></image>
<image v-show="getThemeNum() === 4" src="https://img.forca-world.com/20240626171735940.png" class="cart-img" @tap="openCartPopup"></image>
<image v-show="[5, 6].includes(getThemeNum())" src="{{ getThemeNum() === 5 ? 'https://img.forca-world.com/20240626171735483.png' : 'https://img.forca-world.com/20240626171735346.png' }}" class="cart-img" @tap="openCartPopup"></image>
这样修改后，当getThemeNum()返回值为5或6时，都会显示第五张图片（https://img.forca-world.com/20240626171735483.png），否则显示默认的第一张图片（https://img.forca-world.com/20240626171735346.png）。
