Hey,
I understand that you need help changing the URL of your media folder to an external domain and updating links so that media loads from the secondary domain instead of website A.
Because of my extensive experience in PHP, WordPress and other related applications, I am confident that I can provide the best solution for this project. My skills include understanding how to make changes to URLs using WordPress plugins such as a search and replace plugin, which would be necessary for this job to be done properly.
I'm also experienced with Responsive Web design which would be necessary for making sure all links point to the correct media folders on the secondary domain so they load correctly. Additionally, I have experience working with small and medium businesses and individuals who need help with having a strong online presence and building or boosting their reputation and branding via their website.
Thanks & Regards,
Usama S
