Module development and code questions

I am currently testing out drupal on my local machine before making the dive into switching completely to it. When I tested out posting content through the Comic module, I got the following error:

Fatal error: Call to undefined function: image_validate() in drupal_root/modules/comic/comic.module on line 49

I edited the exact location removing the location of the root but you get the picture. Can someone tell me what I can do to rectify this.

OS: Ubuntu Linux

Hi all
I am using flexinode, and it works beautifully in the creation of the content.
However, when I use the search, and the search results include the flexinode type, the

Using the mail.module and loving it except that it eats of bit of the code when sending a link (both in plain and html options).

Here is some test content for the email and here comes a <a href=ttp://www.example.com" target=self">link</a>.

Hi,

I have a node I've developed that is pretty much entirely custom pages, as it's an interface to an ldap directory and uses no database info. When I click on 'Create Content' in drupal, it gives me the option to add a node of this type. This is totally useless since it doesn't use any nodes, so is there anyway I can remove it from the Create Content page?

User terraces (Alexandre Passant), please leave a comment and turn on your contact form. You have a "tag cloud" module queued for development. Ber Kessels already has the tagadelic module which seems to offer the same/nearly the same functionality.

Please coordinate and submit patches to Ber, or ask Ber if you can become the maintainer.

For a project I'm working on, I've created a new, highly-flexible module for rating nodes. (Yes there seem to be a few of those, but I didn't realize that when I started writing. :-) ) It allows for unlimited user-based rating axes on any node and unlimited "calculated axes" based on those for totals. It's still a bit rough and could use some cleanup and documenting, but it's functional. I'll be adding more calculation options shortly as well, but wanted to get it posted for others to see and offer feedback.
