I would like if someone writes a tutorial on how to build a simple 3D glass cylinder, similar to the following one (apart the color): Many thanks.

Thanks for your suggestion. Can you indicate me some link on how to use Ed Harvey's color effects?

Doing the task manually is a very annoying task, since I have plenty of images to stack, so let me explain my situation. Remember that I am a very newbie. I'm trying to build a meter image to use in rainmeter. The meter is composed by ten plates to be stacked. Now I'm writing out of home, so I cannot show the image of the plate, but it is very similar to the button build in one of your tutorial: . Please note that I want a little trasparent space between the plates, so I cannot use a standard vertical bar to build the meter. Ten of these stacked plates make a single frame; then, I have to consider many different frames changing the plates color. For example, ten grey plates represent 0%, ten red plates represent 100%, while five green plates and five grey one represent 50%. So I have many images to join: for example, if I decide to use 21 frames (from 0% to 100% by step of 5%) they are 10x21=210. Is there an easy solution to this problem?

Using paint.net I have build several (few hundreds of) images that I need to join as a vertical strip into a single image. I was not able to do such a task. Is there some specific command, or can I use an "ad hoc" trick, or batch processing mode? Thanks for your help. P.S.: I have also tried some other program to complete the join task but they fail because my images have some trasparency level.
