Hosting In-House Images

You are responsible for a web site, and need to resize images before sending them to a browser

One approach is to use real-time server-side image resizing, using a utility such as AspJpeg. When a thumbnail or full-size image is needed, the original image is resized and transmitted, but not saved.

The Pre-Sizing Advantage

JpegSizer offers an efficient "pre-sizing" alternative:

You resize images once, instead of on every hit

You have many more options available during resizing

The image processing burden on your server is eliminated

Your server no longer has to store large original hi-res image files

If you are currently delivering high-resolution original images -- without any resizing -- resizing will make your images download to users at least 10 times faster, and your site's bandwidth requirements can be reduced by at least 90%. What's more, you protect your valuable hi-res images from unauthorized use and copying.

Original hi-res image files are typically reduced from 2MB to 50KB -- a 40-fold reduction. This will only get better over time as cameras output more pixels.

Generating Thumbnails

You can do this in real-time with AspJpeg. By resizing the "full-size" images instead of the originals, the computing load has again been reduced at least 90%. This benefit is magnified by the number of thumbnails on a web page.

Pre-sizing thumbnails with JpegSizer has an advantage if your full-size images contain a caption or watermark that would not display well in a thumbnail. In this case you would add the text when you create the full-size images, and omit it when you create the thumbnails.

Thumbnail files are typically only 4KB each, so the additional storage requirements are minimal.

With JpegSizer Pro, you can even create both full-size and thumbnail images in a single run.

Automation

You can use JpegSizer manually, or you can control the Plus version from your own Windows applications (see technical details).

An example of the latter would be a database application where your staff are adding records with images, and the images must be resized prior to storage. A few lines of code in the database program will make the resizing automatic and transparent to the user..

All of the above techniques can be implemented with the standard end-user version of JpegSizer. Customization is available, but is not normally needed.
