There are several on-line album providers around but many have limits. Bubbleshare doesn't, which is quite surprising, so that's a good place to keep copies of all those photos for a start. There's a simple tool to include a small visual display of an album on a wiki or VLE page which will be popular.

At last, some basic Photoshop tools for everyone to use, free, on-line. Smart interface. Upload your photos, arrange them in albums or just edit them and download the new file.

Picasa starts to work as soon as it is installed and provides very easy cataloguing of images on your local PC, particularly valuable these days. A beautifully designed interface includes a range of excellent image editing tools, turning poor pictures into good ones at a click of the mouse. Publishing or sharing a collection is just a few clicks and you don't even need any web space. Similarly, images can be sent to a Blogger web log or e-mailed with resizing performed automatically.

Dfilm is a fascinating tool to create movies online using Flash components. Simplistic in many respects but could prove useful (and would give students some fun creating!). The end result of your movie is emailed to you.

Stuck for a way to get your message across? here's something completely different! Strip Creator allows you to create comic books, and again is a lot of fun to use and may appeal as another way to present some information.Some samples here too.

This has been around for a while, once a special offer for those who validated their Microsoft software but now pretty freely available. Wraps pictures, text and a soundtrack in a nice package that brings delivery to life and creates interest. Big files and a bit clunk but simpler than Moviemaker. Splashcast better.

Here's a lovely application you can just draw, paint, doodle, spray with. It's what we always wanted MSPaint to be and more. Work can be saved in a range of formats for use elsewhere and it will suit all ages and levels of artistic prowess!

The interface leaves a lot to be desired and needs some design input but, boy, the results are impressive! Smarter than Picasa and many reptable and expensive album-maker add-ons to commercial products.
