Can I redownload images without spending credits again?
Yes, with an active MattePaint Subscription and if the image was downloaded in the last 6 months.
When you download an image, the button changes to say "Purchased". Clicking the button again will download the file at no cost.
You will also notice any lower-resolution asset is marked as free and higher resolution options are discounted by the amount already spent on the asset. This means you can purchase any resolution and upgrade to a higher resolution without double paying.
If the image was downloaded more than 6 months ago, you will have to re-purchase the image.
You can also see all your download in your download history.
