If you need specific PDF dimensions (e.g., A4, US Letter, square), **first create a Google Slides file with your desired page size.**\n- Then, select this custom Google Slides file in the **'CopyPdfTemplate'** node (under 'File').\n\n🖼️ **Image & Folder Setup:**\n- In the **'CopyPdfTemplate'** node, also select the Google Drive **Folder** where your source images are located. The copied presentation and final PDF will also be created here.\n- The workflow filters for `.png` images by default. To use other types (like JPG), update the **'Filter: Only Images'** node.\n\n⚠️ **Image Size & Workflow Limits:**\n- Google Slides may have limitations on individual image size and the overall PDF file size when exporting.\n- This workflow works well for smaller presentations (10–20 pages). Larger files may run into errors or performance issues during export.\n\n💰 **Cost:** Free to use (relies on standard Google API calls, which are generally within free tier limits for typical usage)."

The workflow fetches all images (that pass the filter) from your specified Google Drive folder.\n2.  It sorts these images by their creation date.\n3.  For each image, the workflow:\n    a. Creates a new blank slide in your Google Slides presentation.\n    b. Updates the image's permissions in Google Drive to be publicly readable (this is a temporary step, necessary for the Google Slides API to insert the image using its URL).\n    c. Adds the image to the new slide, fitting it to the slide's dimensions.\n\n**Final Touch:** After all images are added, the *very first slide* of the presentation (which is a blank page from your template) is deleted."
