We need to implement some optimizations in our website:
- at the moment, some images are resized on the fly every time you refresh the page; after the modification every different size version of the image must be created and stored when a user uploads the picture.
- save images in two subdomains
- reduce the number of images using css sprite
- change notification settings: when a user registers to the website the default configuration should be: all options active
The website was built using php/mysql.
