I know you said you tried Command Strips and I honestly think that would probably be your best bet. There are some heavy duty command strips for heavier items. However, I found this article which gives you other options for hanging without using nails: https://food52.com/blog/25894-how-to-hang-art-without-nails

Hi Thea if there is no way to hang from the walls would it be possible to hang them from the ceiling?

Thea why didn't the command strips work for you? Did you clean yours walls before using them?

Maybe a larger command strip that can hold more weight or use more to distribute the weight better

Here are some ideas to display pictures that do not require making lots of holes in the walls.

Try alien tape. It's a double sided tape that is much stronger. Also, don't skimp on the amount of tape you use.

Get command hooks and use them to hang pictures.make shure to check weight if the pictures is heavy they go by weight the hooks.

Has he offered any suggestions on how to hang pictures? It doesn't seem reasonable to not allow any type of wall decor. Does your lease state what you are allowed to use?

I wouldnt hang anything heavy from just the surface of the wall. Anchors are best put through the wall into stud.

Perhaps a floor standing rack that is decorative that extends up high enough for pics.....

I personally have had terrible luck with Command strips and hooks. I wouldn’t hang heavy items without holes in the walls so you may have to forgo those but maybe a sturdy double stick tape would work. There are some very strong ones out these days.

Try the Command Strips for outdoors. They are stronger than the ones for indoors and may work better. They also hold more weight.
