I deceided that i was getting tired of using other image converters with hundreds of options i don't need, so i just made my own. It only supports Converting between 9 formats at the moment (and i haven't gotten converting to *.ico to work yet, but left it in there in case anyone else did). Decided to publish it so anyone else that was sharing in my image converter anguish could use this. The image will maintain it's aspect ratio if the form is resized or whatnot.
Edit: By the way, don't make fun of that epic picture, it was one of my first attepmts with my new Wacom tablet!
EDIT2: Re-Uploaded program, found an error in the opening of TIFF images, it's fixed now
EDIT3: Re-Uploaded AGAIN, now the form snaps to the size of the image when it is opened, and if it is larger than the screen, then the form will just maximize for maximum possible area.
