Module development and code questions

I'm having a devil of a time coming up with the appropriate paths for two tasks:

1. I need to get the path/URL to the current module. I want to serve an image in the module's directory.
2. I need to find the absolute path to an image being served in a page. Given the page text, I need to figure out where the image is on the file system, so I can find it's dimensions. I could get the base URL and the I have the URL path to the image (e.g. themes/mytheme/myimage.png), but how do I translate this into "/absolute/path/to/drupal/themes/mytheme/myimage.png)

Hi

I just saw:

http://koivi.com/ie-png-transparency/

It's a GPL'd library to turn all <img src = "foo.png"> into MSIE 5.5+ transparent PNG loads.

I'd like to wrap it into a module. I could make it part of a theme, but I think a module would give people more independence.

I'm afraid I haven't had much time lately to respond to issues for my contrib modules, and I apologize to those who depend on them (particularly pathauto, relative to the 4.7 upgrade). At this point, I'm trying to get away from spending so much non-day-job time staring at a computer screen, and to reconnect with the real world. To that end, I invite any interested module developers to adopt ongoing support for the following modules:

I am going to be using Drupal in an upcoming project. I will need to extend the details that users enter in at login, such as regional information and some other custom stuff. I was wondering if anyone has any good recomendations on how to produce a module that does not make me an island in the Drupal world. I don't want to build this module, and then be stuck in no mans land(ala Mambo). I have a lot of registration info to collect, so I will need to stretch the registration process over three seperate form submittals... anyone have a clever idea for how to do that...?

Hello.

I got a painfull problem: I cant save my drupal-settings under admin/settings. Drupal always states, that "CGI needs to be turned on for that directory", but i haven't enables clean URLs and deleted/renamed the .htaccess-File.

This is the only page that behaves like this - all other pages and/or functions of that drupal-installation work great. I first found this behaviour with an CVS-Head dated 11-20-2005, but it it is still in 4.7 beta3.

Any ideas how i can solve that "mystery"?

Sincerly,

Hi everybody..

Can someone explain db_rewrite_sql and _db_rewrite_sql ?
What are those function used for? Why should I implement them on my modules?

A little example might be clearifing.

Thanks
