All the images in my posts have have absolute links:
WordPress was also located inside /weblog.
But now I moved the WordPress files to a seperate folder in the root, /wordpress, and only kept the index.php inside the root.
So then I made a redirect from /weblog to the root. All the URL's of the images are still the same and they are printed correctly inside the sourcecode. But I guess that when the page calls for an image inside /weblog/images this call is also redirected to the root.
Does that mean I should replace all the URL's inside my database?
I'm asking all this because I read somewhere that it's best to have the first page of a website contain a lot of text instead of a first index.html with only <body onload=... > to the /weblog/index.php.
