Blubox V4 photo-sharing software

Software, websites or FTP

Sharing high resolution digital images with your friends can cause problems because of the size of the files. Not only is it time consuming, but it's also blocking up your friends' inboxes.

That's where compression software comes in. The software temporarily compresses files to make then smaller so they can be sent by email. When the recipient receives the compressed file they simply extract it so the full size file can be stored on their PC.

A number of compression programs are available, the most popular of which, Zip was created over 20 years ago and uses binary compression. However, according to Peter Boswell, CEO of Blubox Software, binary compression isn’t suitable for the large image files that are common today because it barely reduces the actual size of the file when it's compressed.

"Extensive research showed there was a massive gap in the market for software that could offer the ability to significantly shrink their digital photos without sacrificing the high resolution quality of the original image file," explains Boswell.

With this in mind, the company has launched a new program that it claims offers greater compression so users can send whole albums of images in the time it usually takes to email just a couple of images but without compromising the quality of the image.

Blubox V4 is a compression program that combines up-to-date compression technology and industry standard encryption to compress large files by up to 95%. Compression filters determine whether the imported file is an image or a non-image file. The software then uses either binary compression (for non image files) or Discrete Cosine Transform (DCT) and wavelet compression (for images).

According to Blubox, the DCT and wavelet methods achieve a more effective compression. The data is then optionally password encrypted where it remains compressed and secure until it can be exported back to its original format. Pictures are encrypted using 256-bit AES technology and unlike other programs on the market, Blubox V4 lets you view and print the images or files while they are still compressed and is even compatible with all formats of Zip compression programs. The program costs £19.99 and can be downloaded from www.blubox.com.
