How To Create Posters/Canvas For My Art

Hi!
I'm a graphic designer in RL and want to showcase some of my work in SL.
I'm still pretty new to building, but wanted to know if anyone how to create posters/wall art so I can display the works on my wall...I know it's probably really simple so please forgive me - but I'm tearing my hair out searching for how tos!!
Any help is much appreciated!!!!

You first need to upload the file as a texture - costs L$10 per file.

Then create a simple cube prim and flatten it out - then use your picture as the texture for the prim.

Be sure to set the permissions on the prim so that people can't just take a copy (unless you want them to)

[IM me in SL (when it's online) if you don't know how to do this - I'd be happy to help - as would many others I think]

Thank you so much - I'll definitely be in contact if I have any more questions.
