I recently moved my wordpress.com-hosted blog to my own custom domain. For image hosting, I previously always used Imageshack.
Now that I'm on my own server I want to preserve the images permanently, since we all know they'll get deleted on Imageshack eventually.
However, I've got about 400 articles with images in them. So is there some plugin that would, for example, look through every existing article for images, and replace the URL part in front every image filename with one I specify? Then I could just save all images to my server and would not need to go through every single article, replacing the URLs manually.
If there is no such plugin - could anyone tell me how to write one?
