File Usage Limitation Reached for Wordpress site
<p>I have a wordpress site, and it has more that 30k posts.
Every post has own feature image, and each feature image has 10 responsive sizes.
<a href="http://i.stack.imgur.com/GxBxy.png" rel="nofollow">#10076 post has 13 thumbnails</a></p>

<p>So there are about 300k image files, and this reaches to the File Usage Limit(inode limit) of hosting service.

<p>How can I reduce the number of thumbnails?
For example, when we use 2~3 thumbnails, we can store 120k~180k posts.
Well, are there any other hosting services which can store more than 300k files?</p>
