exporting transparent imgs (chanels?)...NO bg colour!

i once exported images (blurred) without any background. I used these in flash afterwards.



I was shown how to do this with chanels or masks but i cant remember the procedure -


again - im looking to save (pict, tiff, ....???) files from photoshop WITHOUT a background colour and keeping opacity (transparent gifs are not good enough).

Can anyone explain how this works - ?


thanks

soh

I am not totally sure of what you need but the only file types I know of that support transparency are GIF or PNG, the latter supports full alpha transparency whilst the former only a binary form.

I am also familiar with the 'cutout' technique often employed in magazine design - but it looks from your post that you require different answers.

Png would be a nice choice for your type of req.

yeah save as png24 - transparent - great quality - biig siize but then again FLASH compresses as jpg if I'm not wrong...
