Thermal images are much the same as regular images on a camera, other than the sensors used are either designed or have filters added to respond to a specific range of the light spectrum.
For instance, most of today's cameras have an infra-red filter built into them to specifically filter out the light range. However, if it's removed, it's possible to be able to take images based on the heat signature of the item being photographed. Although the sensitivity isn't the best, in most cases it'll work. ****************
Methinks the contributor doth confuse thermal with infra-red. I believe the above answer is true for digital cameras only, but such photos are not "thermal" images. Infra-red Photography can also be practiced with a regular film camera, infra-red film and filters to enhance the result also. Either method requires light to be reflected from objects to the camera...a major difference.
Thermography is the rendering of images using only heat as the energy source, which is far below the capability of any light sensitive camera as far as I know. Such a camera has sensors which work whether visible light is present or not. If you can take your ordinary digital camera and render a picture outdoors at night with NO visible light whatsoever, I will eat humble pie.

How can scientists measure the ground around a volcano before an eruption?
sensors and thermal images
Why were adaptive optics developed?
to eliminate the distorting effects of atmospheric turbulence for telescopes on the ground
Which energy increases as temperature increases?
The thermal energy.The thermal energy.The thermal energy.The thermal energy.
Is there a change in an objects thermal energy if the object is at thermal equilibrium?
no
Does thermal energy depend on the amount of a substance?
Thermal energy is heat. More heat is more thermal energy.
Which type of printer uses a special type of paper to create images via differences in temperature?
Thermal Printer
What are Thermal Paper Rolls used for?
Thermal Paper Rolls are used in conjunction with a thermal printer to produce extremely accurate and clear prints of important images, graphs or other documents.
How can scientists measure the ground around a volcano before an eruption?
sensors and thermal images
What kind of printer produces images such as maps and architectural drawing?
Not a thermal printer..
What does a thermal imager do?
A thermal imager is a special type of camera or monitor that sees infrared thermal radiation (heat) and creates images called thermograms from that. Thermal imagers are useful in many different industries including surveillance, construction, medicine and more.
Generates images by pushing electricity heated pins against heat-sensitive paper?
thermal printer
Does 12.7 mm Barret sniper rifle have thermal images telescope?
Not a standard accessory, but one can easily be fitted to it.
Evidence for ghosts?
There are many different peices of evidence of ghosts, pictures videos, EVP's, and images on thermal cameras.
What is difference in thermal register paper and regular register paper?
Thermal paper is used in registers or credit card machines that use heat to impress the images onto the paper, and regular paper is used in machines that use something else, like a stamp. If you want to know which you are holding, then swipe the side edge of your thumbnail across the roll. If it leaves a black streak, it is thermal paper.
Why is red transparent on IR images?
Any infra-red image I've seen displays the opposite. In B&W, that which reflects more IR is whiter in the print, darker in the negative. In color, it's anybody's guess as to how it will reproduce. Note that I assume you are not referring to thermal images, so neither am I.
What are the advantages and the disadvantages of thermal printers of?
A thermal printer needs specially treated paper on which to burn data and images. Such a printer is more likely to be used to print labels on a roll, or in cash registers, but not all ways. Once warmed up, a thermal printer produces good results and is efficient. Saving on expensive toner and ink cartridges is a bonus. A thermal printer can (as far as I am aware) only able to burn black characters and graphics, though coloured paper could be used to give a coloured effect.
Why were adaptive optics developed?
to eliminate the distorting effects of atmospheric turbulence for telescopes on the ground
