# ha noice. TJ: could one of you photoshop wizards guide me on something?
Is there a way to leave part of an image blank so that once published as a jpeg or whatever, the blank area will become transparent/adopt the colour of an image behind it (for instance the different shades of b3ta grey??

# Saving as PNG or GIF is your best bet for keeping a transparent background.

# PNG then.
If the source is good and you're not arsed about file size then that should do the job.

Otherwise you can save as a dedicated photoshop layer - don't know what that would do to filesize 'cos I don't use photoshop, and of course you're then deeply limited in terms of applications that can open it.

I call png.

Please bear in mind that I am no kind of graphic designer, merely a self-taught hack who only uses things for posting here.

# .png retains all the photo quality
so I'd go with that but don't use the png-8 always go for the png-24 whilst bigger filesize yuou will get more colour definition.

Edit I'm pretty sure jpeg2000 ships with CS4 but you have to install it.

# I've been able to do it with a gif.
except there usually seem to be little white bits around the edge which I've not been able to erase.
