[mapserver-users] querymap mode

[Stephen Lime]

So, is there a problem or not? I'm not quite sure what you're getting at. The different 
"querymap" modes behave just like the normal "map" modes in that only an image
is returned. Other wise whenever you use the [img] tag in a template you're accessing
a regular or query map. The only difference is in which template.

Yap, I know. It was clarified a few times on the list.

But In my opinion querymaps are not exactly normal maps.
The way they are generated has some consequences.
Differences are:
-itemquerymap returns just image, not template, so mapserv is called 2 times (first to return template, second to return querymap which is not saved to temporary file)
-map is generated from mapserv parameters used in [img] tag. So to modify map looks like, you have to modify template source. In case of normal maps you modify only URL.
