Module development and code questions

Hi,

I am wondering how would one go about adding something to a node's body on the fly. Say I have something, a picture, that I want to insert at a certain spot within the body of each node on my site. Anyone have any clues as to how that can be done.

Thanks

Has anyone upgraded the Taxonomy Access Control module to work with Drupal 4.6.x?

Hello could you tell me what might account for this user error below, so I can correct it? Ta.

user error: Unknown column 'Array' in 'where clause'
query: SELECT COUNT(*) FROM mz_quotes q INNER JOIN mz_node n ON n.nid = q.nid INNER JOIN mz_term_node qtn ON qtn.nid = n.nid WHERE n.status = 1 AND q.promote = 1 AND qtn.tid IN (Array,Array,Array,Array,Array,Array) in /Volumes/Files/Users/chuee/Sites/drupal/includes/database.mysql.inc on line 66

Is it possible to merge 2 forms into one?
For example I have a seperate module, which has a custom form element, which would be added to the existing comment form.
Is this possible? And how if it's possible? I didn't see any function that can combine 2 forms, or maybe I didn't look enough..

The ability to import rss feeds directly into nodes was a *great* was a fantastic feature to older versions of drupal, with this module. Unfortunately, v 4.5.x and 4.6 break this useful module. Are there plans to update this module to functional status?

I would like to add a filter to the new image module so that within a node you can use a tag like [img] and specify attibutes such as the height and width. Then during the process of converting the filter to a real <img> tag it will determine which size is the best to use that one. Also things like clean urls can be conpenated for by just including the node number.

I was thinking of a tag like [img href="1" width="100" height="100"] would convert to <img href="?q=image/view/1/thumbnail" width="100" height="100">
