This customization will enable images and pdf files to have their previews displayed on the frontend:

• When editing an instance, if the file is an image or a pdf file, a preview image will be displayed.
• When listing instances, a small image will be shown for each instance, this small image will be clickable to display the image in a larger size.

To use this customization the user must use the following description: $file $image or $file $image([width:value,replaceFlag:(true|false)])

The arguments width and replaceFlag are optional.

width is the width of the displayed image. replaceFlag shows and hides the button to upload another file.
