Transferring a PSD File to Mail Chimp

Hi,

I purchased a PSD File newsletter template for use on MailChimp. I have updated the file and added to the template as I have basic knowledge with Photoshop. I then changed it to a HTML file and uploaded it to MailChimp but none of the information (i.e images and writing)is being recognized on MailChimp.

I would like to change the file, so when I update it I can just upload it each time to MailChimp without needing an expert!

I gather this would take someone that knows what they are doing about 10 minutes, hence the price.

Help would be much appreciated.

Thanks.
