Module development and code questions

I've got a client that wants to integrate ecards in his site. Simple images with text laid on top is not sufficient.

He's got this package in mind: http://ecardmax.com/

From the looks of it, that package has no sort of API or other method of easily integrating it into Drupal. He wants to at least share user auth info between ecards and Drupal in general.

Hey guys,

I installed and configured Drupal 4.7 with no problem. I wanted to try out the e-commerce module and so i downloaded them and create the tables, no problem.

I wanted to use the "image module", and when i decompress it, i get the following error:

Fatal error: Only variables can be passed by reference in /home/jgeek/public_html/drupal/modules/image/image.module on line 730

Does anyone know about this? It seems to be around this line:

I have two problems with the image module:
1) what OS permissions should the images folder have? as my hosting is not displaying uploaded images.
2) seems the image module is generating a link with the full URL, but all links work with a relative (base url + url) way.
Thanks in advance.

How do create table for show in internet explorer????

My organization is hosting a summer camp and we want to set up an online registration system where families can decide which classes they want to take, submit their registration info, and pay the registration fee online. Taking a look at the different modules available, it appears that the best option is to use the ecommerce module and add each class as a "product". This is relatively straightforward, but the problem arises during checkout. I need to capture additional information. For example, a family may have three people who wish to attend the summer camp.

mlm (mailing list manager) doesn't seem to send the subscribe message to an external ezmlm server. Has anybody had any success with it? There is absolutey no documentation on it.
