#1 folder plugin manager #2 file upload #3 database management

#1 Yesterday I followed instructions for upgrading on Podz site (now running theme called ‘Carrots’. Very nice Podz. But instructions said to delete several files and folders. Yet I could not remove the plugin manager folder (Before it wasn’t working anyway). I created another folder and installed 1.5 there.
Now I’m trying to delete the plugin manager, it won’t delete, I changed file permissions by setting atributes. But I cannot remove it with Leech FTP nor Dreamweaver.

#2 When I upload a picture with my fresh 1.5 I get this code but it’s faulty: <img src=’;http://www.georgelangenberg.com/wordpress/wp-content/2005/randompicture.jpg&#8217; alt=’a random picture’ />
Is this a bug / who knows the fix?

#3 Another question. I like to see a picture in every post on my blog. I store my pictures in a folder. But wouldn’t it be wiser to use the MySQLdatabase for this… yes/ no?
If yes how do I do that, If no…
Why not…
