How to set up and use images in slscart

Apr 17, 2017 by Doug DePrenger

Images are a core part of an e-store. There are many image settings in slscart to accommodate.

Optimizing images

The first task is to optimize an image, which means making the image look like the original but reducing its size. tinypng.com is a handy website which does just that. Just drag and drop the image(s) to optimize in size into the site's target area and it will optimize them and provide a download link for each one. Note the image's dimensions (width and height) are not changed.

This task is important because search engines, notably Google, penalize websites that load slow. Reducing the size of images will help tremendously to speed up a website.

Site Settings

The following settings determine where specific images are kept. It is best to use the default locations so all images do not end up in one location. Too many images in a directory can slow down a site as the server has to search for a requested image.

Thumbnail Dir: - default: images/thumbs. This is where thumbnail images are kept.

Large image dir: - default: images/items. This is where the large product images are kept.

Blog Image dir: - default: images/blog. This is where blog images are kept.

Category img dir: - default: images/categories. This is where category images are kept.

General img dir: - default: images. Catalog images, ... are kept here. In very old versions of slscart, all images were kept here.

Catalog Setup

Item images: - default: 3. This setting determines how many large images are available for a product (up to 5).

Related images: - default: 'no'. If 'yes' then up to five related images (with links to related products) can be specified for a product. The product's thumbnail image is used. If 'no' then links to related products are used.

Max upload size: - default: 400 KB. This determines the maximum size of an image that can be uploaded to the server. 400 KB is quite a large image. The range is 100 KB to 2048 KB.

Use Alt Keywords: default: no.

Upload Width: - default: 200px. This is the width of an auto created thumbnail.

Upload Height: - default: 200px. This is the height of an auto created thumbnail.

Max image width: default: blank. If blank, the actual width of thumbnail is used. Enter the maximum pixel width at which your thumbnail images should display, or leave blank to use the actual width of the thumbnail.

It is best, performance-wise, to have the thumbnails the same size and not enter a max image width or height.

Max image height: default: actual height of thumbnail (i.e. leave blank). Enter the maximum pixel height at which your thumbnail images should display, or leave blank to use the actual height of the thumbnail

Item Thumbs: When uploading item images, choose between the default setting for thumbnails offer to create an auto thumbnail, use the large image, or show a blank thumbnail field?

Thumb Defaults: When uploading item images, should the aforementioned setting apply only when no thumbnail image exists, or always (adding or replacing thumbnails)?

Thumbnail Crop: When uploading item images, if the 'Automatic thumbnails' choice is selected, should the 'crop image' button be checked by default? (Store admin can still choose to crop or not; this only affects the initial default setting.)

Images

Image list

Uploaded images are managed from this.

Catalog images

Images can replace links in the store's catalog. The images are stored in the general image directory.

Included are:

Favicon images

A favicon, many years ago, was a simple file called favicon.ico and placed in the home (root) directory. That was before mobile devices. Now, there can be literally dozens of images. Apple uses touch icons, Windows 8,10 uses tiles, Android uses ?, and safari uses svg graphics. They have different dimensions and requirements.

slscart can create nearly all the favicons. Click here more information on creating favicons in slscart.

Layouts

There are several ways images can be shown on the product detail page. The default is stacking the large images.

Under 'Detail Image' is a dropdown list of the different ways to display the large image(s) on the product detail page.

Important notes: A mouseover zoom is replaced with a regular pinch zoom in iOS devices. Zoom and Lightbox options are only available with plugins. Using slideshow, gallery, lightbox or zoom options add some load time to the site, especially if they are utilized on a single, double, triple or multi layout; use in detail product layout only is recommended.

Pages

Nav Image: If you want to display a button image instead of a text link (if you are using text link navigation types), click the Upload link to load an image. You can also add a second image for a mouseover effect, if desired.

Header Image: If you want to display an image at the top of the page, in place of the page title, click the Upload link to load an image. This image will only display if the "Show Title" field is set to "Yes".

The list image also displays in place of the category name for any sub category listing. Enter the URL of the list image here. You may also click the image to load a new image to your site.

In the Description: field images can be inserted.

Up to five large images can be specified for a product.
