How to delete uploaded images

how can I delete the images that I have uploaded to be used as an example the background of a form ?

Greetings.

If you wish to remove images you have used as a form background, you can open Form Designer, and under the Colors tab select Choose a File under Page Image. This will open a new small window. You need to click on the My Images tab, select the image you wish to remove, and confirm by clicking the Delete button:
