Comment:

I have a jpeg image which is in color when viewed as a thumbnail in imaging progrmas such as Zoombrowser (a Canon program) but switches to B/W when I try to view it or print it full size. I haven't a clue why this is? Any ideas?
Thanks, Jack

If it's not a private picture you could email me a copy and I could check it out for you if you wanted?

Is the image from a camera?(which camera)
Downloaded from internet?

Have you tried opening it in windows picture viewer or any other program?

Try the XP viewer and see if it is the same. This will at least tell you if the problem lies with zoom browser or with the actual jpeg.

Remember that zoombrowser is not like the xp viewer or thumbnail view. XP renews its thumbnail view automaticaly with any kind of change using any program. Zoombrowser won't renew the thumbnail unless you do it manually or you have used zoom browser itself to alter the jpeg.

So if you used another program (accidently orotherwise) to alter the jpeg in question (convert it to b/w), then the zoombrowser thumbnails will have to be renewed manually. (there is a REFRESH switch there somewhere, just can't remember where)

I've used Windows Picture and Fax Viewer and itshows it in B/W but there isn't any thumbnail feature that I know of in that program. Is this the same as the XP viewer you speak of?
I really don't think I accidently converted it to B/W.

To prove I'm not smoking something funny - I created a print screen image/word doc of the zoombrowser page showing the color thumbnail.

Indigan: I'd be happy to email the image and the print screen doc to you or anyone - what's your email address?

As far as I can make out the ICC profile is corrupt.
The thumbnail view is in color because it does not use all of the ICC profile's information.

I'm not sure why it is/got corrupted?

not sure what an ICC profile is, but thanks - I'll see if the source can resend.
