Error File upload + Spam

[zjootsuite]

Since a fee weeks I have the update 1.5 running. But I can't upload any pictures. I don't know what to do or what I did wrong;

Error
Something's wrong in file upload!

On my latest upload on my photoblog (http://zjootsuite.com/zjootsuite/zblog/) from 2006-08-27 21:34:10 I recieve lots of spam.
Again: I don't know what to do or what I did wrong.

Please help...

Did you upload all files from 1.5 package in ASCII mode through FTP?

Do you upload JPG files?

Put here data from general tab in admin panel as we want to know were can be a problem (and it helps to find some of them).

@GeoS: I did some reading in my General Info file and I see this in Paths:

Guessed imagepath: /home/novioplan.nl/public_html/zjootsuite/zblog/images/
Configured Imagepath: /home/junitiv.nl/public_html/zjootsuite/zblog/images/

Image Directory: Does Not Exist (should be /home/junitiv.nl/public_html/zjootsuite/zblog/images) - Thumbnails folder not writable! You must set correct permissions on this folder or you will not be able to upload any images.
Set the folder to chmod 777 (read, write and execute permissions for owner, group and world).

Thumbnails Directory: Does Not Exist (should be /home/junitiv.nl/public_html/zjootsuite/zblog/thumbnails) -

Language Directory: Does Not Exist (should be /home/junitiv.nl/public_html/zjootsuite/zblog/language)

Addons Directory: Does Not Exist (should be /home/junitiv.nl/public_html/zjootsuite/zblog/addons)

Includes Directory: Does Not Exist (should be /home/junitiv.nl/public_html/zjootsuite/zblog/includes)

Templates Directory: Does Not Exist (should be /home/junitiv.nl/public_html/zjootsuite/zblog/templates)

I changed my server from junitiv.nl to novioplan.nl. I have all the directories on the new server. But how and were can I change the configured imagepaths so that everywere junitiv.nl will be novioplan.nl?

Thanks in advanced.
