I've been focusing on my problem number 1.
I've looked through my config file and compared it with my old one(s). I see nothing new there that would make the images not appear. The setting $rcmail_config['show_images'] is set to 0, which means "Never show images, always ask".
But I've stumbled uppon some other problems as well now, so I guess there is something wrong with the installation itself.
I could not enter my addressbook (blank page, have not looked for any errors). And one time I got timed out while on that blank page. When I then logged back in again, the loginscript tried to redirect me to the page I had been on (it said in the url), the addressbook. When I got logged in, all my folders was messed up. Every sub-folder was showing up in the "root" menu.
So, I guess I can conclude there is something wrong with my installation.
The next question I have is: How do I proceed if I am gonna do a fresh install (if I want to keep all my addresses/mails/folders/settings) ? The mails will still remain on the IMAP server (if I have understood correctly?), but the rest is stored in the database, or?
If I replace all the files, would that count as a "fresh install", or do I have to remake the database as well?
