Hello, I'm wondering if someone made CC of a painting or print that is the same subject and shape but in different sizes, and if where I can find it.
Thanks!

There are tons of different varieties of the different EAxis paintings, such as the Pineapple painting, BV Travel poster, and the various other posters and pictures found ingame. I think they've all been tinkered with at some point, put in different frames, resized, repo'd, recolored, you name it. Depends on how big/small you need the pictures, and how many sizes, I guess?

Anything in particular you have in mind?

My favorite is the BV travel poster. There's tons of different sizes, shapes and recolors, and it fits pretty much everywhere.
(Google "BV travel poster sims 2" - there's too many results to link)

I didn't have any clear idea in mind, except maybe 1 and 2-tiles versions of the same painting. The Pineapple painting could do what I'm thinking of, any idea where I could find tinkered versions of it, or at least what keywords to look for?

There's one ingame picture called "surfing the pineapple" and another called "Lady on Pineapple".

Found several links here (use search function Ctrl+F and write "pineapple", there are 4 links on page 2), but unfortunately they lack pictures: https://sims2artists.com/index.php?topic=5126.15 (also, to make the box links work, switch "www" for "app". Some of the Dropbox links don't work).

There's several links for other pictures too, so you could have a loook through it and see if you find anything of interest.

Have you considered using SimPe's Photo Studio tool to make your own pictures using whatever subject you like? You can use any graphics tool (even MS-Paint) to crop or resize your image(s) to fit into the various different in-game provided picture templates.

There are also additional templates for various EPs available (https://modthesims.info/showthread.php?t=43450). I've made a number of photos of various sizes using different templates. It can be rather fun to do!
