NopCommerce: Image size constraints

Question

Using NopComm 3.90.

Is there a way in NopComm to set an image size constraint?

In Config -> Settings -> Media Settings, I can set the size of the images, but from what I gather this is setting default sizes of images? I need to set a hard constraint on the image sizes that our publishers will have to abide by. Thanks.

If you are using default picture upload in admin panel this method gets triggered during picture insert

/// <summary>
/// Validates input picture dimensions
/// </summary>
/// <param name="pictureBinary">Picture binary</param>
/// <param name="mimeType">MIME type</param>
/// <returns>Picture binary or throws an exception</returns>
public virtual byte[] ValidatePicture(byte[] pictureBinary, string mimeType)
{
    using (var destStream = new MemoryStream())
    {
        ImageBuilder.Current.Build(pictureBinary, destStream, new ResizeSettings
        {
            MaxWidth = _mediaSettings.MaximumImageSize,
            MaxHeight = _mediaSettings.MaximumImageSize,
            Quality = _mediaSettings.DefaultImageQuality
        });
        return destStream.ToArray();
    }
}

If you set "MaximumImageSize" in media settings nopCommerce will auto resize large images.

Setting a constraint to enforce a specific minimum picture size does not exists. But you could easily create a plugin for that.
