The system base on our CMS formerly called FlexicaCMS and a new shopping cart module which is 100% Yii base, written from scratch.

Good job, but the image resolution is too large. It is too slow to open the image.
Thanks for pointing that out, need to tell the client. They manage the images.
Ohh okay, but my suggestion, you should restrict max image file when user upload the image file,
for example each of image file max 100Kb. It is to prevent reduction of website’s performance.
