Batch mockup

Loll, you were looking for hours (like 3 - 4?) for replacing logo in 70 mockups that would take you 70 minutes, so one minute per template. Take money from client for designing logo, but for additional tasks so placing logo manualy to mockups ask him to pay you extra 🙂 I believe it is tiresome, but at least you don't take money for nothing, so if script did that for you.

Just brwose forum again for script / action that for each template in folder it opens it to place (& resize) logo.

There are also good examples of such simple tasks in documentation if you'd like to understand scripting.

There is no standard design or layer structure for a Photoshop template. You need to not how the templates are used and add the logo so it does not mess up some automated process that may be used to populate the templates.  You can not just place in you logo as the top most layer.  You cans add your logo to image files created from using the templates.  If your 70 mockup templates have a similar design you may be able to record an action to the add your logo to a one of your one mockup template.  Then batch the that action for the remaining 69 templates.  The action may be able to use my Photoshop PlaceLogo script you can customize to place your logo into a template sized and positioned for the template's canvas size. Then the action can position the logo layer in the layer stack where the layer will be visible in the mockup template output composite and not compromise the template design. The action needs to end with a File>Save to save the layered template then close the template document opened by the batch process.  You may want to save the templates to a different location so the action will not change your original templates..
