Images

Detailed description of all options

Here you can see settings for different image sizes and different content types in the form of a table.

The types are:

• Categories: Image for the categories displayed in JTL-Shop. This is used, for example, in the navigation and on category main pages. Category images are maintained in JTL-Wawi in the category master data; see Category images
• Variations: For variation items, the variations can be displayed as graphics. As soon as you select a variation in the parent item, the variation images are the same as the normal item images. Please note that for parent-child relationships, child items are considered as separate items.
• Items: The images that were stored for the item in JTL-Wawi, please see: Images.
• Manufacturers: The image stored for a manufacturer in JTL-Wawi; please see: Creating manufacturers.
• Characteristics: The image stored for a characteristic in JTL-Wawi; please see: Creating and editing characteristics.
• Characteristic values: The image stored for a characteristic value in JTL-Wawi; please see: Creating and editing characteristic values.
• OPC: For images added in the OnPage Composer, see: Inserting images with the OPC
• Configuration groups: The image stored for a configuration group in JTL-Wawi; please see: Creating configuration groups
• Blog: The images you deposit in JTl-Shop in blog posts; please see: Setting up a blog.
• Blog categories: The image you store for your blog category as a preview; please see: Setting up a blog.

Picture sizes Mini/Small/Normal/Large: Here you set the default resolution for all available image sizes.

JPEG image quality: Your images are recalculated in each of the different sizes. Here you set how good the quality should be. You can enter a value from 1 to 100. The higher the number, the larger the file. Usually, the predefined 85 percent setting is sufficient. With higher quality settings, it is possible—depending on which programme was used to create the original images—that the images recalculated by JTL-Shop are larger than the original files.

Image names of item, category, variation, manufacturer, characteristic and characteristic value images: Here you can define how the name of images is to be generated.

Enable external image interface: Here you can grant access via the image interface to everyone, only JTL-Wawi or no one. The image interface is a kind of API that can be used to find out the image links for specific items.

The following parameters are available:

• “a” for the item ID (kArtikel from the tartikel database table)
• “n” for the image number
• “url” 1/0; controls whether a URL or the image is output
• “s”: Choice of picture size (1 for “lg”, 2 for “md”, 3 for “sm”, or 4 for “xs”)

Match image size to container size: Images are usually displayed in a frame or container in JTL-Shop. With this option, images are automatically scaled to the size of the container. If the aspect ratio of the image does not correspond to the setting, bars in the background colour appear at the edges. This would be the case, for example, if you specify an image size of 320×320 pixels but do not upload a square image.

File format: Here you determine the format in which your images are to be saved. JPEG, PNG and Auto (Automatically; also create .webp) are available for selection. If you select Automatically and the server allows this, all images are also allowed in webp format. This requires additional memory on the server, but webp images are much smaller and improve performance in the front end.

Background colour: Here you can select which colour the bars should have if you have activated the option Use container size and the images do not have the same aspect ratio as the set image sizes. These bars are only displayed if your images are not square.
