Module development and code questions

I've added the Image and Filestore modules to my drupal site and have activated the modules. After a bit of work on directories, they work.

i am using drupal 4.4.0 and associated modules with same version.
Iam not able to save images in the database , I get an error like

"warning: Rename failed (No such file or directory) in /home/sites/site1/web/drupal/modules/image.module on line 719.
Cannot save image."
There's no problem with the premissions of the directories

When I try to preview an image that I'm uploading on a new drupal site with the just installed "image" module, I'm getting the following error message. Does anyone know what might cause this?

warning: move_uploaded_file(./tmpimg_dharma-posse.jpg): failed to open stream: Permission denied in /usr/www/users/mimir/ngakpa/modules/image/image.module on line 463.

warning: move_uploaded_file(): Unable to move '/usr/tmp/phpOUeGsv' to './tmpimg_dharma-posse.jpg' in /usr/www/users/mimir/ngakpa/modules/image/image.module on line 463.

I'm building a module that allows users to create content.

In drupal, every node has a title. However, in the module I'm making, the "title" is not needed and asking for a title is confusing to the user; all they need is to input is the "body".

I don't want a title input field to appear to the user in my module's gui. How to get around this?

The only way I could figure, is to hack node.module, and insert a conditional statement that tests for my module's name.

If the test for my module name is true, the title input field will not appear to the user.

I have recently installed Drupal and have been quite pleased with its capabilities. I'm interested in creating a site that would require users to submit content over several pages. I would be asking for a fairly large amount of information from my users which is the reason for the multi page submit process.

Two questions:

Just a simple and stupid game to keep your users busy. :)

It's just like the 'game of tag'.
