Need Help with Image Embedding in Google Slides via Make from Airtable URLs

It doesn’t look like your scenario is setup properly (and you probably don’t need that repeater module), but I can’t specifically tell you how to cleanup the scenario without playing with it myself.

In the meantime, I give a demonstration on working with arrays in Make in the context of Airtable attachments on this Airtable podcast episode:

I need that repeater because in every single ppt presentation, I want no more than 6 logo images.

Also sharing a screenshot of how the URL is being pulled.

I used the same script for a mailchimp campaign as well (minus Google slides of course) and the images are being pulled correctly. Even here all the other details like name, website, description etc is being pulled correctly. The issue is only with images. 

Hmm… the exact same scenario sent the images correctly to other modules, but not to Google Slides? If that’s the case, I would open a support ticket with Make and be sure to report back here with what they say!

p.s. I just noticed this note on the documentation page for Make’s Google Slide modules — does any of this apply to your situation?

Note: The images must be less than 50MB in size, cannot exceed 25 megapixels, and must be in one of PNG, JPEG or GIF format.

I have added the same query in Make community as well. Waiting for their response. Thanks for the suggestion! 
I even checked the constraints. The image is max 20 kb , so well under the mandated 50 MB, is around 200 pixels (again under 25 megapixels) and in the png format. However when I check the url, I don't see it ending in the png format. Is that possibly the reason? Is there a formula that gives the url with a file name ending?

That is very likely the reason!

I think that Airtable automatically includes the extension if the original file had the extension, but I’m not sure. I’m not at my computer right now to verify this.

I tried a workaround. I replaced all tags with placeholder images and then used a 'Get a Presentation' module to retrieve the object details. I finally used 'Upload an Image by replacing an image' in the Upload Image in Presentation module. And it worked. Looks like the tags aren't been recognised. 

Wow, that’s a great discovery! Can you please report that to the Make team for them to investigate?

Yes, certainly!
