Description
There is absolutely no need for all this sort of code in the module's hook_init:
function linkimagefield_init() {
// If Content, FileField, or ImageField is not available, immediately disable Link Image Field.
$disable = FALSE;
$message = '';
if (!module_exists('content')) {
$disable = TRUE;
$message = t('The Content Creation Kit needs to be installed for it to work properly.');
}
The .info file's dependencies list guarantees that this module will not be enabled without the required modules.

Question: what does Drupal do if those dependencies are disabled or uninstalled while linkimagefield is still enabled?
Does drupal fail gracefully or does it throw up the white screen of death?
#2
The module admin page won't let that happen; nor will drush.
If a system admin goes changing the system table by hand, then it's their problem, and it's not up to modules to account for that.

First thing I thought when viewing the .module.
Patch attached, the include modeled after how filefield includes it's filefield_widget.inc
