The Arial.png file is the default for text, you don't need to load it to use it. And it might not be impossible that you are confusing the system.
What is the value of intFontImage?
And, try this order of commands (I left in your font commands just to be sure we used the same set of commands as you started with):
LoadImage(intFontImage, "Arial.png")
SetTextFontImage(1, intFontImage)
SetTextColor(1, 0, 255, 255, 255)
SetTextSize(1, 5)
SetTextAlignment(1, 1)
SetTextDepth(1, 1)
SetTextPosition(1, 50, 1)
How is it not appearing correctly?
