Creating multiple NPCs at once

I am serting up a new campaign with many NPCs I currently have 24 NPCS I am trying to create for a campaign - each has 1 portarit - file named the name of the NPC 1 token - file named the name of the NPCS Is there a way I can upload all of these at once? currently I am havnig to add NPCs 1 at a time in Roll20 then rename, add portrait and then add a toke, it is time consuming

Hi Snake,  Nope...creating NPCs can be time consuming.  Your best bet is to make a baseline campaign with all the NPCs in it, then duplicate that for your active campaign. That way you don't have to repeat the work.  Note: this assumes you are not using a game system which has NPCs pre-made in the Compendium. In that case I would suggest using the Compendium versions for any NPCs which already exist.  Note2: If the NPC is a duplicate of another NPC, two Orcs for example, you do not need to recreate them, just copy/paste the token after creating the first NPC. 

I would also add to unlink the status bars(HP, AC, Move, etc.) on the "Original" npc/monster before copy and pasting additional mooks .
