I need help with summuning macro

Hello everyone ! I'm pretty new to Roll20, and i never used macro before. I'm trying to achieve something (i think) simple for those who are mastering it :) My players have some summoning powers (weapons and beasts). I made Rollables tables for each power where every item which can be summon is listed. For now, i just use it in background to randomise the summuning. But i want to add a button accessible by players so they can launch their summuning by themselves, and when they do it just show on the map an illustration linked to the item they summon. I donno if i'm very clear :D Thank you for your help !!

You can't create token objects with a click unless you have api access, so I suppose what I would do in your case is create a rollable table token (make sure that the box is checked to allow players to roll from table), and assign it as the default token for a character sheet (called "Summons" for example), then give player permissions in the character sheet for In Journal and Controlled By. They could later drag the "character" out to the map, then right the token->Multi-sided->Random Side. The roll will show up in chat and the token side will change to the corresponding image. You could add token actions within the Summons character sheet to roll relevant attacks, etc., though this could get cluttered if you had a lot of summoning options.
