Uploading PNG files that are not visible without a dark background
Hi! It’s my first time uploading PNG files to a stock website, and I’ve run into an issue: light-colored images are hard to see on the white background.
I’ve noticed that some other authors upload PNG files with a semi-transparent black background. However, the upload guidelines state that there shouldn’t be any background. What’s the correct way to handle this situation? There’s no option to upload a JPG preview or select the display background for your PNG files. Can I add a 90% black background directly to the PNG image?
Thank you!
