I had migrated my website from Joomla to WordPress with "FG Joomla to WordPress premium"
the problem is that I have more than 2900 posts in my website they all are now imported in WordPress version but images in my posts are linked like this:
example.com/postname/articles/image.jpg
but in WordPress images should be like :
example.com/wp-content/image.jpg
now I all my 2900 posts images are broken and not shown.
I decided to redirect it but I don't know how to that cause it's variable post names !!
I highly recommend an extension called RegularLabs DB Replacer. The free version should do what you need. Just go to the com_content table where Joomla stores the articles, and in the introtext and fulltext fields and you can do the find and replace there. I also recommend switching the image src= to relative paths instead of absolute paths that contain your domain name in them.
