Need help with digital portfolio CD -cross platform?

[wovenpaint]

I want to burn an art portfolio to a CD using this criteria - "All digital images must be a minimum 500 pixels wide, maximum 1200 pixels wide, and 72 DPI (dots per inch). Digital image files must be one megabyte or smaller. All digital files must be able to open cross platform on Macintosh & PC computers. Test your media before sending it in."

I have them on a PC and they're jpeg format in the specified size. My question is about the cross platform. If I burn a CD of the individual photos on my PC, will it open cross platform on a mac automatically. If not, how do I make one that will?

TIA-your help is greatly appreciated!!

1. I'm not a mac person, but... jpeg is platform independent, I believe

In any case, it's such a universal web format that I'd be surprised to find any computer that couldn't render one.

.tiff is another very universal format, but can be HUGE

2. JPGs are fine ...

That's really kind of a weird way to describe the criteria.

As long as you have software on any system that can read a certain file format, that format is for all intents and purposes cross-platform.

I'm guessing what they don't want is some proprietary file format associated with a specific piece of software that won't open with anything but that software. I see this a lot more with music files than with digital images, but that stuff is out there.

In any case, I haven't seen software on any platform in years that couldn't open a .jpg file. The JPEG standard has some limitations if your purpose is high quality image reproduction, but it'll work for the purpose described.

3. Thank you!

for your help. The wording of those directions did throw me off as I had been thinking that the jpeg was universally used...but I work with PCs, so didn't know if I was just assuming this. Thanks again...

4. jpeg should work fine.

If it's all about the photos, they are probably having trouble with proprietary camera, document, and presentation formats.

To preserve the quality of your photos or other artwork, you'll want to adjust the jpeg quality settings of your photo software as high as possible while keeping the size of the files under one megabyte.

It's possible people are sending them art arranged with some sort of proprietary presentation software like PowerPoint. Some of that software doesn't play as well or at all cross platform.
