[miisss xia]

Trello helps so much and is very handy, easy to organize and this is what i am exactly looking for to have, and to enjoy it more i wanted to change the background to my own edited backgrounds, i even searched how though i already saw how just to make sure, but I can't click the +custom box, i can click the other options like the colors and pictures already ready for trello users but i can't click/open/use the custom one.
what am i going to do?

Hi @miisss xia , in addition to what @Deepanshu Natani shared, you can also do custom backgrounds with Trello Gold, and you can get up to 12 free months by recommending Trello to friends and family. Here is more information:

Hi @miisss xia 

In order to personalize your board by adding your custom background, you need to upgrade to Business Class.

If you are using free plan, you wont be able to do that.
