[mapserver-users] PNG, which Netscape Version

[Ed McNierney]

Chip -

It looks fine on Netscape Communicator 4.78 on Windows 2000
Professional.  What version of Netscape (and what OS) is giving you
trouble?

Sure... the problem is on my test box (which is private), however, the
issue
seems to be the same on our public server as well.

Can you put this up on a public server we could look at?  I'm serving
PNG images from an IIS/Win2K server to Netscape clients all the time...

Thanks Ed...I had read that, and couldn't figure out whay my images
weren't
working in Netscape (still can't for that matter). Probably should've
offered up some more info from the beginning.

After some experimentation, this seems to be an IIS (IIS 5 on Win2k).
I'm
trying to view some PNG images in NS. If I put a png file into an HTML
document (using the IMG tag), I can open the file directly in NS, and it
works fine (e.g. I open c:\myfiles\png_test.html in NS). If on the other
hand, I try to bring up the file throught the web server (e.g.
http://localhost/png_test.html) it comes up as a broken link in NS.
Either
way works fine in IE. I can view the PNG images through NS on the libpng
test page as well... so, it seems fairly certain that this is a
"feature" of
IIS.

I found something on libpng about fixing this (basically adding an entry
for
PNG to the MIME map in IIS), but this does not seem to have helped.

Any ideas would be helpful... if I figure it out, I'll post.

Chip

Chip -

Generally, version 4.04 and above.  For all the gory details (along with
other PNG application support info) visit

Can anyone tell me the minimum version of Netscape required to view the
flavor of PNG images that MapServer produces?

(I'm using PHP / Mapscript with the 10/10/2001 dll from DM Solutions).

Thanks!
