If you want to delete an image that you've uploaded to Qwilr, you can follow these steps.
Step 1. You can delete images from 2 places in your image gallery. To get to the gallery, click on a + symbol in any block. Then choose Image from the menu that pops up.
Step 2. From there, head to either the Recently Used or Your Uploads sections.
Step 3. Hover over the image you want to remove. An X icon will pop up. Click on it to remove the image from your media browser.
Note: Deleted images will remain visible in any projects that they were used in. Deleting an image from the media browser only removes it from that location.
