How to upload images to the file manager
Your File manager is where you store all the images that you upload and use in your campaigns and forms. It can be found in your dashboard sidebar.

Here, you can click the Upload image button to import an image from your computer into your file manager. Or, you can click the downward-pointing arrow on the right-hand side of the button to import an image from a URL, Google Drive, Giphy or Iconfinder.

If you select URL, a window will appear. Paste the URL of your chosen image into the input field to import it.

If you select Google Drive, a window will appear that allows you to log in to Google Drive and select images directly from your drive.
Giphy is a similar resource. Though, rather than supplying an endless library of static images, you can choose from a huge range of GIFs to add to your newsletter.
Iconfinder is a marketplace for icons, illustrations and 3D illustrations in SVG, AI, and PNG format.

My image is larger than 2 MB, how do I upload it?
Larger images load slowly in your subscribers' inboxes. Also, if they're using their mobile internet, larger images result in bigger data usage.
Additionally, the smaller the image, the less likely your newsletter will land in spam or the promotions tabs.
For this reason, your images must be under 2 MB.
If your image is too large, you can use an external tool to compress the image.
