Images are not appearing in magento cms editor

I worked on a magento project on which cms images were not appearing in editor and also on front end.
CMS editor was getting image urls like http://your-websitelink.com/media//imagename.ext because of double slashes (//) images weren’t appear on front end as well as in cms editor.

I searched on internet but didn’t get any useful info that can solve this issue so I came up with a solution to use php functions to handle this.
Open file /httpdocs/app/code/core/Mage/Adminhtml/controllers/Cms/WysiwygController.php
Change $url variable from

$url = Mage::getModel('core/email_template_filter')->filter($directive); 

To

$url = substr_replace(Mage::getModel('core/email_template_filter')->filter($directive),"",strrpos(Mage::getModel('core/email_template_filter')->filter($directive),"/"),1);

Save it.

For front end I made static blocks for different images for different pages in left column those had same issue I fixed it same as above but used static block code as following.

$block = substr_replace($this->getLayout()->createBlock('cms/block')->setBlockId('block-name')->toHtml(),"",strrpos($this->getLayout()->createBlock('cms/block')->setBlockId('block-name')->toHtml(),"//"),1);
echo $block;

By above statements image url will not have double slashes.
