big graphics

[zoomby]

hello!

Does someone know how to speed up the handling of big images (around 2 MB), or is php just slow in this case.

Another question: Does someone know a server/tool (BSD) which can manipulate images faster than php?
I'm thinking of a big map which should be partly loaded. The user could then navigate in this map, (no applet)
like in a online street map.

Thanks for all help...

look, 2MB communication, in a slow connection like 56 kbps, means you have to wait 256 seconds (4 minutes) in a optimal scenario.

You can't improve that communication until you have a good connection speed to the net.

Hi,

I'm not talking about diplaying images. I mean the time the server needs to manipulate an image using the PHP image functions...

You could always try ImageMagick, but I'm not all that sure it would help. Manipulation of large graphics is very processor and memory intensive.

Is there any way you could pre-generate and display on demand? ______________________________________________________________________

Hi,

Thanks for the help. Here is what I want to do in detail:
I have a big, 2mb map of a landscape with cities and bus stations. I want to offer the user a comfortable way to navigate in the map (zoom, scroll etc via links).
The same system, like I want it, can be seen here:

Any tips?

cut the map into loads of small bits, number them all very carefully and reconstruct the reuired bits as required.

mySQL and PHP should do this in a fraction of the manipulation time of something like the GD library. ______________________________________________________________________
