Change view product opencart

Using version 1.5.1, and want the products to be displayed on the site as the 2.x version. How can I do this? What must change in category.php, CSS, etc.?

Do you have a picture below how I want it to occur.

Up ?

This 'kind' of PIC's are part of the Font Awesome, used on OC v.2x Versions. you would therefore have to add this FONT Awesome into your system, or call it from an external Site. Then, you would have to add this 'routine-link' into your Header Section, and then, you would have to re-code your category.tpl Souce Code, and/or other sections, where you want to see this Style, to make it work. So, it's a lot of work, waiting for you...

The cheapest alternative, to have it look like OC-2, would be, to buy the Theme mentioned below!

This is an OC v.1.5.6.x Custom Theme, looking like OC v.2.x, and you can see in detail here:

After having some problems, in the beginning, I just re-downloaded and installed the latest Version of it, to check
it on Function, and as far as I can see, PEKU (PM-NETTI) has been doing a good Job since, to make it work well.
It may still require some little things, like language Variables, but the DEV is a nice fellow, and he works hard !
I just installed it, and added a couple of (language-related) missing things, otherwise, it looks as it comes, by default.
There are one or two still to fix minor error-messages, but basically, it works well!

Oc2 Theme to version 1.5

Just to give you an idea !
Anything else would be much more complicated to achieve...
But I am very unsure, if it works with your OC Version as well !!
