This website is for trading of spectacles/glasses, contact lenses, sun glasses. A CMS like Jhomla or something else can be used.
It will have main sections such as:
Children Eye wear

The admin section should be used to enter product details and upload images(big) of products and it should automatically create thumbnail(using PHP gd library) and store it in two separate directories.
The thumbnails should be used to show the products in search results and bigger image should be used while displaying the products details.
In the admin section there should be provision to say the categories of products and some particular category/categories can be displayed in Exclusive Sale and Special Offers pages.
Please see that you are to develop a software and hence the changes for the software will be there as we proceed with the development.
