master page logo not displaying on new web form within subfolder

I am new to masterpages so bear with me if this is a stupid question. I have a master page that has the company logo image on the top of the menu bar. I created a new web form with master page. After I created the new page I moved it into a subfolder called berkeley_heights. When I view the page in chrome it shows the menu bar but not the logo image above the menu bar. How do I resolve this issue.

Solution

Could it be a relative path issue? i.e. Your logo's src is "img/WebsiteLogo3Transparent.png" - that'll show on the home page. e.g. www.site.com/img/WebsiteLogo3Transparent.png

Once the page calling the MasterPage is in a subfolder, the browser expects that subfolder to have a folder called "img" within it. e.g. www.site.com/subfolder/img/WebsiteLogo3Transparent.png

Test this by adding domain to the source or change the image tag to

<img src="~/img/WebsiteLogo3Transparent.png" runat="server" />"
