Using the Imagizer Plugin
Most people would like to be able to upload photos directly from their cameras. The problem is... Each off camera photograph will probably have a resolution in excess of 4000px. x 4000px., with a corresponding file size of greater than 3MB. If you loaded many of these images into your web pages, your page access times would become very, very, slow. As using such large images also wastes both disc space and bandwidth, pre-processing them to a smaller size makes sense.
Just what size is that? Well that rather depends on where it is being used, with the main constraint being the width of the content area of your web pages. A usual size is around 600px in width.
What about images for galleries? Common image sizes for web galleries include... 600px , 800px and 1000px.
Note: Here the dimensions given refer to an image's maximum dimension in either height or width.
To setup Imagizer log into GetSimple Administration and go to the Files tab. Select Imagizer on the RHS menu to access the configuration page. See the screenshot...
Imagizer will resize all images above a preset size so that their largest dimension - in either width or height - is equal to the preset size. In the case shown 800px for a web gallery. The plugin will also resize any image that is below a preset size as well. If for example you entered 200px in both 'Minimum Size' fields, Imagizer would increase the size of all images below 200px - in either width or height - to 200px.
Remember... Imagizer is always active so bare this in mind every time you want to upload an image and set an appropriate size in Imagizer or disable it via the Plugins tab in administration.
