Website Optimisations, bug fixes and updates

Optimisation of website for mobile devices. By detecting screen resolution and sizing content accordingly to improve user experience. There are two parts to the site, the main content plus the shop section running on Opencart. Both sections need work. Ensure all the existing functionality and modules keep working. After user login, the page should redirect to the original place where the user clicked the login link. (this is a bugfix as it stopped working after an opencart update) Highlight the password field on the registration/login page so that users clearly can see they need to enter a password if they do not want to just proceed as a guest for checkout. Save and re-upload more optimised images for the main ones such as header image. We sell some custom one off items, but opencart is not great for this. I already have a custom mod that allows a product to be added that only a specific user can buy. However, this still appears in the "latest items" on the home page. I would like the addition of a simple checkbox field on the product editing page that flags that an item is "Custom Item" and prevents it from loading in the latest products section. Users have suggested the main RM logo in the upper left should be clickable to link to the homepage. This will just need a simple bit of css/html
