LG Image Preview v1.0.0 Thumbnail previews of weblog entry images in the CP

Introduction

LG Image Preview is a Multi-Site Manager compatible ExpressionEngine extension that adds a small thumbnail preview to weblog entries in the control panel edit page. The thumbnail is generated from data in a weblogs specified custom field if available.

Each weblog has its own thumbnail settings including which custom field to mine for the image url, thumbnail height and width, an option to link to the original image in a pop-up window and wether to show a thumbnail at all.

This extension is very similar to Ryan Masugas Weegee ExpressionEngine extension and is released publicly with his blessing.

Thumbnail Settings

Each weblog has its own thumbnail settings. The per weblog settings are:

• Image data source
• Thumbnail width
• Thumbnail height
• Quality
• Link thumbnail to original

Image data source [required]

Choose the custom field that stores your image url or a block of text containing a standard image tag with src attribute. LG Image Preview will attempt to parse out the URL and create the thumbnail.

Thumbnail width [optional]

The thumbnail width. If this setting is left blank the thumbnail will be resized to maintain its aspect ratio based on its height.

Thumbnail height [optional]

The thumbnail height. If this setting is left blank the thumbnail will be resized to maintain its aspect ratio based on its width.

If both height and width are blank the thumbnail will be created using the default size of 50px x 50px.

Quality [required]

Quality is used to reduce the file size of the thumbnails and only affects .jpg files. This setting accepts a value between 1-100.

Link thumbnail to original [required]

If set to yes, when the thumbnail is clicked the original image will be displayed in a new popup window.

Check for updates?

LG Image Preview can call home and check for recent extension updates. This feature requires LG Addon Updater.
