Firefly automatically resizes all images so that you don't need to worry about editing images before you use them.Even if you upload a high resolution image, Firefly will make sure that when someone wants to view it on a page, the image will be a suitable size for the viewer's device (and data plan).
Uploading images to Firefly
Firefly has no built-in upload size limits and offers generous timeout limits so that you can upload your images with confidence. The only thing to be aware of is that the better your own Internet connection, the fast you will be able to upload. If you try to upload a lot of images on a poor connection, it may take a long time. If it's too slow or you have problems, it may work better if you try later or using a different connection.
You can add as many images as you'd like to a gallery. However, in order to ensure that performance is as optimal as possible, we would recommend breaking down a large gallery into several smaller ones.
When preparing images to create navigation, Firefly will automatically resize and crop these to fit correctly. If it's important that the focus of the image remains in the centre, then you'll need to edit your image so that it has roughly the same aspect ratio as Firely uses (3:2).
Creating a visual blog
If you've opted for a visual blog, make sure the images you're using are at least 550px by 300px or they won't be displayed.
You can quickly edit your image directly in Firefly.
