There is a one way to have a GIF like animation, but it is a little clunky. I've used it to have a simple little pixel fire animation on my DM430.
Step 1. Extract the individual frames of the GIF file using a tool, I just used an online one.
Step 2. Create an image list in the screen editor project library, add the individual frames to a sub folder, and then edit the image list to include the frames from the sub folder.
Step 3. Add the Image list to the screen area and then set the ActiveIndex property to an input signal.
Step 4. Add an oscillator and a counter to increment the ActiveIndex of the list every x milliseconds, mine was every 40ms, some of the frame split tools will tell you what the delay is.
