Read the manual <https://en.wikibooks.org/wiki/OpenSCAD_User_Manual> , checkout the examples, then understand the lithophane OpenSCAD code on Thingiverse here <http://www.thingiverse.com/thing:74322> and here <http://www.thingiverse.com/thing:78719> .

Should be quite straightforward. Create a single JPG or PNG with all your images in the appropriate places to wrap around the cylinder. Then go to Thingiverse and search for my item "openscad wrap image curved surface". Sorry, I can't figure out how to get a hyperlink on my phone. You'll also need Python. Use Python to generate a. Scad file, then openscad to make an STL.

It's going to look something like this: (this code will not work as written) files=["image1.png","image2.png","image3.png","image4.png"]; //all of these files MUST be png, and MUST be in the same directory as your scad file height=//height of lampshade radius=//radius of lampshade thickness=//thickness of the lampshade inner_radius=radius-thickness; translucency=// a range from 0-1.01 which will change the thickness of relief of the images, depending on if you want a lithophane or a cutout difference (){ cylinder1();//outer cone cylinder2();//inner cone for(i=[0:len(files)-1]){ translate()//center the image rotate([90+atan(height/radius),0,i*360/num_images]) //rotates the image from facing up to facing normal to the lampshade, and rotates the images around the z axis resize([,,thickness*translucency]) surface(file=files[i]); } That should get you started. If you cant do it, I'll write it up and put it up on thingiverse.
