Сохранить TImageList в файл со всем содержимым

// There are ready-made methods for saving any component including all its children to a file.
// For writing components use WriteComponentResFile(path + source filename, component name source)

WriteComponentResFile('C:\imagelist1.bin',imagelist1);

// For reading the data back to a component:
// component := ReadComponentResFile(path + source filename, component name traget)

imagelist1 := ReadComponentResFile('c:\imagelist1.bin', nil) as TImagelist;

// Tip 1 - Reading the component will give the same name of the component written so don't try to
// load it to another component, even if it was the same type. You will get a duplicate name and
// delphi will crash. But you can jump over this as a programmer

// Tip 2 - Get benfit of storing the heavy components inside compressed files,
// so you can get smaller programs
