Thanks for your help. I think i'll just get another hdd. I didn't know about that prefrences thing, thanks. I love how photoshop (and other graphics programs like 3Dsmax) always have new things to learn... the programers and dev team have done a really great job putting these software pacages together.

The "enter" picture's file size is a bit large, use file>save as for web in photoshop to fix that problem... you should be able to get it down to somewhere of half the file size it is right now. The same goes for your main logo which is a big hard to read. The light blue text is also a bit hard to read... but thats not really much of a problem. To be honist the only magor problem is the un-nesacery file size of all the pics. You could save probably a bit by making some of the pics in your ps tutorials as gifs. A back to top link at the bottom of your tutorial wouldn't go astray either. I like it

Alright hers how you do it. Start with a blank canvis. Use the gradient tool to create a black and white gradient. Click on filter>>render>>diference clouds. at this point press crt + f untill you find a pattern you like (the black bit is where the lightning will show). When your happy with the difference clouds then press crt + i (this inverts the image) then press ctr l (please note that is not a one but an L...) this opens the levels options window. Drag the middel up faceing arrow all the way to the right and you are left with your lightning. All you need to do now is change the colour (optional). Press crt + u (saturation) and in the window that pops up play around with the settings. Click the colorise check box if you want the lightning to be a colour. BTW if you move the saturation window somewhere where it allows you to see your image then you can change the colours in the saturation window and see what affect that it has. Hope this helps... if you have any questions then email me

Thanks. That refreshes my memory. I have a different way of doing it though but you got me started by reminding me the basices like Fill etc. Thanks
