The picture step allows users to choose from a preselected list of JPEG and PNG images to add to their design. Images are raster based PNG's or JPG's/JPEG's that you can curate for use in workflows. The difference between images and illustrations is that images are raster based, meaning you cannot change the color of them and they loose quality if you enlarge them. On the other hand illustrations are vector based and can change color and be resized to anything.
There are many reasons for uses images when building a workflow, such as:
Build lists of curated images and offer customers the ability to customise products using images perfectly setup to portray the finished product. Also images used in this process mean that you also can control the quality of the output (printing).
Use images for product thumbnails where another asset doesn't make sense. E.g. illustration patterns that fill a specific area on the canvas can be displayed as pattern thumbnail image. In a question step where a users choice isnt visually represented on the product display like sizes or extra options, you can use images to provide a visual representation of the users choice which displays below the step.
Product Overlays - Where you have a specific product based overlay (Eg. MSDS for chemicals, Barcode or Product based information in general) that needs to be dropped into a workflow that is used across multiple products.
Silent Illustrations - Where you have a design that is used is a background or as a base image that the user cannot change.
Cannot change colors like illustrations because they are raster based Build options using the following option types (illustrations, question step and any product image within an option)
PNG's and JPG's/JPEG's
