To begin uploading images from your Mac, first click "Photos" to the left of your project (the uploader will pop up automatically for photo books and calendar projects).
Then click to open your file finder and access your images.
NOTE: Collage.com only accepts image in jpg or png format under 10MB. PDFs or other file types must be converted before uploading.
Your Photos library will be located under the Media section of the file finder. Select the photos and click "Open" to add them to the project.
If you cannot locate your photos there, you can first save the images to your desktop and then upload them to Collage.com from there.
To do so, open Photos on your Mac, and then simply drag the photo you want from your photos there to your desktop or export the album of photos to your desktop.
Drag and Drop
Export an album
To export an album from Photos, first create an empty folder on your desktop. To create a folder, right click any open space on your desktop and click New Folder. You can then name the folder or leave it untitled, as long as it's there to save to.
Next, open Photos on your Mac and open the album you want to move to your desktop.
Once the album is open, highlight all the photos from the album by clicking "Edit" and "Select All". Then, click "File" at the top of the screen, click "Export," then click "Export x photos."
Now, select the folder you created on your desktop in the file finder to export your photos to that folder.
To upload those photos to your Collage.com project, open the file finder as described in the beginning of the article and look for the folder and photos under the "Desktop" section of the file finder and upload the photos.
Select the photos and click "Open" to add them to the project.
