Codeigniter resizing EXIF standard images

[quote author="InsiteFX" date="1394527725"]Your web host may not allow the eval php statement, check with them.

Its think its allowed because for the other images its processing the eval function and I get resized images. Example 10 ads get resized images and in the 11 ad post the resize is not happening. As I can see in my file manager the images which is not resized are like the type mentioned on my first post.

I will check the php version and I will check with my provider.
More help will be appreciated.

Thanks
