Need to change image and text based on value in clicked hyperlink - PLEASE HELP!

[heffalump]

Hello,

I have a MySQL table with columns for Comment, Name, Occupation, CommentType. I would like for the text in the Comment field to be displayed depending on the CommentType selected on the web page.

#1: How do I have it in a hyperlink that a value for CommentType is given and then compared to the data in the MySQL table, and then display only those records where the CommentType = the value in the hyperlink?

#2: I need to do the same in #1 but now include images with the text that is queried and displayed. I plan to add a column to the MySQL table for the ImageLocation. But how do I code to have the actual image retrieved with the text?

Thanks to any and all who can help...I'm pretty much a newbie, but was not sure if this is a newbie-level question. I've searched the web but must not be using the right keywords.
