MY apology, I posted this without making sure I was in the right forum.

Sorry!

[JPG and need background to be transparent]

I have a JPG which is a black and white line drawing I want to drop this on a collage where the line drawing shows, but the background must be transparent so other things come through. Essentially, I want to turn the color [ or lack thereof] white to be transparent, and black to be black.

I haven't got the foggiest idea how to do this, or if it can be done.

Any thoughts?

[Fade to background]

You guys are the BEST!

I can fade, then save as both a JPG and PNG. both are excellent. The JPG takes up less than 10% of the file space, so I go with that,

But the real point is that I was given help FAST, and excellent. I am delighted to be aboard this forum.

[Fade to background]

Changing the opacity from the F4 box is exactly the effect I am looking for. Two questions arise from that:

1) Where would I find information leading me to use F4? Is this an unpublished feature?

2) As I fade the picture out, I am getting a checkerboard effect. please foegive my beeing fussy, but can that checkerboard be dimished, or is that just inherant in fading?

Thank you all for your very kind assistance, I appreciate it!

[Fade to background]

I have a picture that I want to use as a very muted background [ in a web site]. There will be text over it, so the picture needs to be toned down [ is that the right phrase?] so it is background material, not interferring with reading text, but still there.

I've played and played, but I can't do it. Probably silly simple, but what you don't know can be a mountain to climb.
