How to upload a logo for each language and the dark theme and set image sizes for products, categories and brands in the Trust template for OpenCart 3.
Logos and sizes of all storefront images are set on the “Images” tab of the template settings: Octemplates → Trust OCTemplates - template settings.
Logos
- Logo — for each language and separately for the light and dark theme. Shown in the header and footer. If not uploaded, the default store logo is displayed.
- Footer logo in light theme and in dark theme — which of the uploaded logos to show in the footer: the regular one or the dark theme one. If the dark theme logo is not uploaded, the regular logo is used.
Tip. Upload the logo as SVG — it stays sharp on any screen. The dark theme and dark footers (Main, Compact, Mega) need a light version of the logo.
Image sizes
Width and height in pixels for each image type. OpenCart creates copies of photos in the required size, so the site doesn’t load unnecessarily large files.
| Image | Where it’s shown | Default |
|---|---|---|
| Logo | Header and footer | 180 × 44 |
| Subcategory | Subcategory tiles above products | 60 × 60 |
| Category | Image in the category page description | 180 × 160 |
| Manufacturer | Brand logos | 60 × 60 |
| Product image thumb | Gallery on the product page | 800 × 800 |
| Product image popup | Enlarged photo in the viewer | 800 × 800 |
| Product list | Cards in categories, search, modules | 228 × 228 |
| Additional product images | Thumbnails under the product photo | 80 × 80 |
| Related products | Related products block | 228 × 228 |
| Compare list | Compare page | 90 × 90 |
| Wishlist | Wishlist | 100 × 100 |
| Cart | Cart thumbnails | 100 × 100 |
| Store | Store photos on the contact page | 360 × 320 |
Aspect ratio. If product photos aren’t square (for example, clothing at 3:4), set sizes in the same ratio — say, 600 × 800 for the main image and 228 × 304 for the list. Then photos won’t have empty margins.
