NivoSlider

Hello everyone. I know this is not new and there are a few posts about this subject on the forum. I have read them all. Unfortunately, they are all outdated. I am using nopCommerce 4.60.3. And I have updated nivoSlider from 5 images to 15 images according to the outdated posts by using Visual Studio 2022 on Windows 11 Pro. Voila! Of course, it does not work :))).  The error message is :
'PublicInfoModel' does not contain a definition of 'Picture6Url' and no accessible extension method 'Picture6Url' was found that accepts an initial argument of type 'PublicInfoModel' (could you be missing an instruction directive or assembly reference?)
However, I did what prabirchoudhury said on this post. Also, I was careful & followed the references that write on VS. Besides, VS cannot find any issue or warning. I believe this happened because of something beyond the source code. But what?
PS: bolds are folder names, italics are file names.
I added the required changes "PublicInfoModel" in the folder Plugins/Nop.Plugin.Widgets.NivoSlider
Components
WidgetsNivoSliderViewComponent.cs
The changes I have made are:

var model = new PublicInfoModel
            {
                Picture1Url = await GetPictureUrlAsync(nivoSliderSettings.Picture1Id),
                Text1 = nivoSliderSettings.Text1,
                Link1 = nivoSliderSettings.Link1,
                AltText1 = nivoSliderSettings.AltText1,
                .
                .
                .
                Picture5Url = await GetPictureUrlAsync(nivoSliderSettings.Picture5Id),
                Text5 = nivoSliderSettings.Text5,
                Link5 = nivoSliderSettings.Link5,
                AltText5 = nivoSliderSettings.AltText5,

                Picture6Url = await GetPictureUrlAsync(nivoSliderSettings.Picture6Id),
                Text6 = nivoSliderSettings.Text6,
                Link6 = nivoSliderSettings.Link6,
                AltText6 = nivoSliderSettings.AltText6,
                .
                .
                .
                Picture15Url = await GetPictureUrlAsync(nivoSliderSettings.Picture15Id),
                Text15 = nivoSliderSettings.Text15,
                Link15 = nivoSliderSettings.Link15,
                AltText15 = nivoSliderSettings.AltText15

                if (string.IsNullOrEmpty(model.Picture1Url) && string.IsNullOrEmpty(model.Picture2Url) &&
                string.IsNullOrEmpty(model.Picture3Url) && string.IsNullOrEmpty(model.Picture4Url) &&
                string.IsNullOrEmpty(model.Picture5Url) && string.IsNullOrEmpty(model.Picture6Url) && 
                string.IsNullOrEmpty(model.Picture7Url) && string.IsNullOrEmpty(model.Picture8Url) &&
                string.IsNullOrEmpty(model.Picture9Url) && string.IsNullOrEmpty(model.Picture10Url) &&
                string.IsNullOrEmpty(model.Picture11Url) && string.IsNullOrEmpty(model.Picture12Url) &&
                string.IsNullOrEmpty(model.Picture13Url) && string.IsNullOrEmpty(model.Picture14Url) &&
                string.IsNullOrEmpty(model.Picture15Url))

Also, I've made the necessary changes to some files like that which are :
Controllers
WidgetsNivoSliderController.cs
Models
ConfigurationModel.cs
PublicInfoModel.cs
Views
Configure.cshtml
PublicInfo.cshtml
Plugins/Nop.Plugin.Widgets.NivoSlider
NivoSliderPlugin.cs
NivoSliderSettings.cs
Presentation\Nop.Web\Plugins\Widgets.NivoSlider\Views
Configure.cshtml
PublicInfo.cshtml

It was working fine before these changes. Any suggestion would be appreciated. Thanks

So you need to edited the PublicInfoModel and added something like the following for each new image ?

        public string Picture6Url { get; set; }
        public string Text6 { get; set; }
        public string Link6 { get; set; }
        public string AltText6 { get; set; }

You are talking about PublicInfoModel.cs in the Models folder. Yes, I added every single one of the new images.
