How to remane inserted image in Velo

Hi all, I recently started working on Velo, I now came across a problem I cannot figure out myself. How do I rename an inserted image. My images get the standard name #image1,2,3,… but to implement them into code, something else would be easier for future.

You mean to change the item ID (it is not the name of the file).
To do it, click the image, and change it in the property panel (see in red circle)

Just to follow up on this. In order to see that section you have to make sure that Dev Mode is turned on (on the top left)
