Beginner – ASP.NET Core – How do you deal with images and similar media in a back end?

I’m new to back end programming with ASP.NET. I’m wondering how to deal images that are either taken with the users camera or just uploaded with their gallery. At the moment I have a nice little ‘DeliveryItem’ object with things like Strings for name and Ints for quantity and all that, but essentially what I want now is public image ItemImage { get; set; }.

Convert webpage to image from ASP.NET

I would like to create a function in C# that takes a specific webpage and coverts it to a JPG image from within ASP.NET. I don’t want to do this via a third party or thumbnail service as I need the full image. I assume I would need to somehow leverage the webbrowser control from within ASP.NET but I just can’t see where to get started. Does anyone have examples?

Resizing an image in asp.net without losing the image quality

I am developing an ASP.NET 3.5 web application in which I am allowing my users to upload either jpeg,gif,bmp or png images. If the uploaded image dimensions are greater then 103 x 32 the I want to resize the uploaded image to 103 x 32. I have read some blog posts and articles, and have also tried some of the code samples but nothing seems to work right. Has anyone succeed in doing this?
