I missed which is your OS. Anyway since there is no installer for IMGDissolver, there is no uninstaller.
When you download it you simply unzip the archieve and launch the IMGDissolver.exe file. If you want to uninstall it, then delete the directory where you have unzipped the archieve. That's all, IMGDissolver does not write anything inside windows registry, ev variables etc.
Best regards
