One thing I know that will cause some of the problems (and this issue has
been raised before on this newsgroup) - if you use any of the following:
1) Word Art or
2) Any picture format besides GIF or JPEG and perhaps PNG (not sure about
this one),
3) "Iincompatible" files might be for example MS Word (Windows) files that
won't open on a Macintosh (I don't know if Microsoft have a Mac version of
Office (?). Generally if you save a file as ASCII text in Windows (eg
notepad) then it can be opened on a Mac in one of its text editors I would
think. But anything else is pretty much application-specific.
Some browsers (if not all) will not display the image, or display rough
representations in gif format (in the case of Word Art), or not display the
word art at all. I've tested WordArt in 4 browsers for windows - IE
displays it as a VML object, but Opera, Netscape, Firefox display a GIF
version
Mac Users of the above browsers would probably get mixed results; I don't
know about Safari.
However if you must use Word Art (not saying that you are, or even intend
to, I'm just trying to narrow down the problem you're having and suggesting
a possible scenario and solution), then by all means create it, place it in
a page in FP, then take a screen-shot of the screen (Print-Scr)
Paste it into your image editor, and crop it down to just the word art
element. Save it as a jpg or gif, and then insert that into your page,
rather than using the word art element itself. That will increase the
likelihood of 99.9999% of people being able to view it, including Macintosh
users.
Other file formats other than GIF and JPEG might not be viewable (and will
be bigger in file-size hence slower loading).
Also, there's some issue with the "type" of jpegs - make sure they're RGB
colour format not CYMK (or some related issue like that).
There's also the issue of different hardware platforms treating colours
differently (this is just a guess, based on the wide range of graphics cards
and monitors available).
It may not just be a browser issue but an operating system and platform
(hardware) issue i.e. PC vs Macintosh or Windows vs MacOS vs Linux etc.
Can you give more in depth detail about the types of files that are
incompatible, etc? Maybe members on this group with Macs using Safari can
also check and give an extended description of problems they receive?
Hope this might help you out
