Module development and code questions

how can i give every OG a image logo and let the image logo display in “my group” block and “new group” block?

i notice that the new 'node_revisions' table is using 'vid' as its primary key. which seems to be needlessly confusing, since vid is already the primary key of the vocabulary table. i was looking into the history and found this:

Hey all

This has been driving me absolutely crazy for about two hours now... All I want to do is pass an image file to the browser, however I can't use print theme('image', '/tmp/image/hello.jpg'); because it's not visible to the webserver... Surely there's some (easy) way to pass an image for output, or do I have to file_copy it to the tmp directory just so it can have a web address?

I've created a custom node type and am trying to create a form for it.

I'm creating a form where the user can click a button and elements (a text box and a check box) are added to the form. They can then submit a variable number of items in one form submission. I figured that if I used the right format for the field names (edit[name]) then the data would just show up in the node magically. Unfortunatly, this doesn't work because the forms API doesn't know about the extra fields.

Someone can suggest me a solution?
