Module development and code questions

I have installed the pdfview.module but if i use it there is the following error: Unsupported image type: gif

In the fpdf docs i found that only jpg and png images are supportet :-(

Do you know a solution to fix the module so also gif-images will be shown as pdf?

An example of the error message: http://www.ebec.net/pdfview/view/1 from http://www.ebec.net/node/1

greetings from germany, holger

I am writing a module right now that changes the theme. This is a site specific module, so the only two themes are a "high bandwidth" theme and a "low-bandwidth" theme.

On each page I am generating a link back to that page that allows the theme to switch. For example. if you were at mysite.com/about, then there would be a link a to mysite.com/lo/about, which when you click on it, the theme changes to the low bandwidth version.

I am in the process of writing a module that will take a date as part of creating a node. If there were a form_date() function, I would use that. Because there isn't, I'm here asking for advice.

What is the best and most consistent way to create a date entry on a form?

Thanks for your help!

Has anyone got the gallery.module working with Drupal 4.6.2?

When I try I get a blank page at mysite/gallery.

My local task menu items seem to be alphabetizing themselves rather than appearing in an order I add them. Is there any way to override this? How?

Error - "the document contains no data" when i try to attach a file or image.
