Definite solution for portrait image request

Dear support, we have a bigger problem with the listing images. For our type of dyrectory we need to have all the listing with Portrait images.

Please can you give us the solution ? Is most important to us that all listings became portrait. Please can you share to us some snippet ad instructions to make this ?

We have made some test with css but the result is bad because the image is little into the listing box. We are sure that with a couple of change intonthe listing template function and other file this mod is possible. Please help us in order to speed up our development without spend a lot of hours to understand how make this mod. You have developed the framework and you sure know better how produce this mod easier and fast.

We’ve searched a lot into the forum in order to find a solution but your replies are the same ever. please give us a workflow and the snippets to do this mod, a lot of clients need this we are not the first.

Thanks in advance and best regards
Massimo
