Module development and code questions

I want my users to upload images... but not delete them.

How do I configure Drupal so no images can be deleted ? Supprisingly the permissions don't let you disable image deletions.

This seems to be a image.module issue

Hi! I'm trying to develop a module which allows people to view a list of users with the data from their profiles in a sortable/searchable manner. I also want people to be able to control what fields they see. My idea is to create a page that would look something like this:

Fields to display:
[X] Last name [X] First name [X] Email [ ] Phone number  [Change visible fields]

Last Name V    First Name   Email
LN1            FN3          ...
LN2            FN2          ...
LN3            FN5          ...
LN4            FN1          ...
LN5            FN4          ...

I'm not worried about searchable right yet — I'm still trying to get sortable working. It sort of works — I can use the form above to change the visible fields, but then all the sort information is lost. And if I use the links at the tops of the tables to change the sort information, the displayed fields is lost. Somehow, I need to be able to take the current display information, and insert it into the links generated by theme('table', ...). I also need to take the current sort information and save it across calls to the separate form.

Hello there,

Some of my site's users, randomly, are getting this error message:

Duplicate entry 'menu:2:en' for key 1 query: INSERT INTO cache (cid, data, created, expire, headers) VALUES ('menu:2:en', 'a:3:{s:10:\"path index\"; a:164:{s:11:\"admin/block\"; s:1:\"2\";s:16:\"admin/block/list\"; i:-2;s:21:\"admin/block/configure\"; [...]"admin/comment\ in /var/www/includes/database.mysql.inc on line 66.

Even if cache is disabled, what doesn't make any sense for me.
