I need help with layers!

I pulled up an image in PS CS3 to edit (Tiff file). I added a few designs using a couple of different brushes. And I also added text. It's for a birth announcement. Now, when I try to open it using iphoto (for a slideshow) OR when I try to open it with my Press Products (CPQ), it won't open! All of my images (that haven't been edited with brushes, etc.) appear. The images I have edited appear but I cannot click on them... their numbers, etc. are faded.

The only place I can open them is PS CS3! I have tried saving them every which way. One thing I've noticed is it says something like "File must be saved as a copy"... and then it has an exclamation mark beside the Layers box... but I CANNOT click on the layers box to 'save as a copy', etc...

What do I do? Help! I've never experienced this with CS2... on my PC. I have to have this birth announcement ready by this week!

TIA,

Andrea,

Not sure I'm following. Did you try to flatten the .tif and save it under a new name?

Neil

Did you compress it?

You know you have slideshow features in Bridge, right?

yes, I flattened it and tried to save it under a new name, etc... when I try to pull it up in iphoto or anything else it shows the file name, etc... but I cannot click on it to open it. The only place I can open these pics is in PS CS3... Thank you for your response! I'm going to try a few other things... if you have any suggestions, that would be great! :D

Yea, I know I have a slideshow in bridge but I like the iphoto options, etc... My main problem is that I cannot open the pictures in my press products for ordering... or anywhere else. The only place I can open them is in PS CS3. I would like to do a slideshow too but my main thing is getting these images ordered. :D Thank you for your response! Have a great day. :D

If these are 16-bit images, change them to 8-bit.
