Load the images into image list, display in Form and save

The details depend on the image and file formats you want to support in your application. For example, if you want to display only natively supported image formats, such as JPEG, PNG, GIF, etc. you can create a .NET panel control, enumerate all files in the source folder that contains your images, create different picture box controls and add these picture boxes into the panel, and then you can load each image in a picture box control.
This way you will have an image list control that contains different picture boxes on a panel.

But if you are looking for creating an image list control that can different images and document formats, such as PDF, DOCX, TIFF, JPEG, BMP, etc. you can use the .NET LEADTOOLS DocumentViewerThumbnails class with the Document Viewer from control to manages and display the thumbnails.

The following code shows how you can create a LEADTOOLS DocumentViewer in your Windows Forms application with thumbnails:

protected override void OnLoad(EventArgs e)
{
// Create the UI of the application. Two panels, one
// for the thumbnails (on the left) and one for the view (fill the form)
var viewPanel = new Panel { Dock = DockStyle.Fill };
this.Controls.Add(viewPanel);
var thumbnailsPanel = new Panel { Dock = DockStyle.Left };
this.Controls.Add(thumbnailsPanel);
// Create the document viewer using the panels we created
var createOptions = new DocumentViewerCreateOptions { ViewContainer = viewPanel, ThumbnailsContainer = thumbnailsPanel };
var documentViewer = DocumentViewerFactory.CreateDocumentViewer(createOptions);
// Set some options, such as Pan/Zoom interactive mode
documentViewer.Commands.Run(DocumentViewerCommands.InteractivePanZoom);
// And view the documents as SVG if available - no rasterization
documentViewer.View.PreferredItemType = DocumentViewerItemType.Svg;
// Load a PDF document
var document = DocumentFactory.LoadFromFile(
@"C:\Users\Public\Documents\LEADTOOLS Images\Leadtools.pdf",
new LoadDocumentOptions { UseCache = false });
// Set in the viewer
documentViewer.SetDocument(document);
base.OnLoad(e);
}
