Hi! There are alot programs and websites that offer thumbnail making. But alot of them are scams or just dont work. Today i am going to tell you what programs and websites do i use! I use Adobe Photoshop. It is a great program but it coasts money. You can get a 30 day trial once you sign in. Free website that i use is PicMonkey. You should definetly check it out, its great and its working. If you find better programs for use of thumbnail making just reply to this thread. Thanks for taking you time reading this! Lukas!
