My code right now plots a function, and animates an image moving along the curve of the function. I want to reduce the size of the image for this animation but I can't figure out how. If I try to change 

image = Import["image.png"]

to

image = Import["image.png",ImageSize -> Tiny]

it just makes the image blurry in the animation. This is the animation code:

Animate[Plot[{f[z]}, {z, 0, 50}, 
  PlotRange -> {{0, 50}, {0, 10}}, 
  Epilog -> Inset[image, {x, f[x]}]], {x, 
  0, 30}]

Does anyone know how to fix this?

  • $\begingroup$ Although this is dealing with an image, the actual focus lies on the Inset, which is discussed here:Scale Insetted Characters to Plot $\endgroup$

Use the fourth parameter of Inset:

enter image description here

f = Sin[#] + 5 &;
image = ExampleData[{"TestImage", "Lena"}];

Animate[Plot[{f[z]}, {z, 0, 50}, PlotRange -> {{0, 50}, {0, 10}}, 
  Epilog -> Inset[image, {x, f[x]}, Automatic, 10]], {x, 0, 30}]

You can also use Show with the option ImageSize:

image = Show[ExampleData[{"TestImage", "Lena"}], ImageSize -> 40];
f = 5 + Sin[#] + Sin[Sqrt[2] #] &;

Animate[Plot[{f[z]}, {z, 0, 50}, PlotRange -> {{0, 50}, {0, 10}}, 
  Epilog -> Inset[image, {x, f[x]}]], {x, 0, 50}]
