I just noticed a change in the way my blog images shrink when clicked. I don't know when this change occurred, but I am certain things used to be different.
For most of my images, it used to be that when you clicked on it the link would send you to a larger size of that image. I would normally set it up this way so that the image (sometimes with charts/numbers) would not take up much space in my post, but could be enlarged for careful inspection.
Now, when you click on the image you are taken to a smaller size version of it. It's seems to be a consistently small size. This is a problem because it makes many of my charts or similar images unreadable.
Typically I upload a "full" size image, then shrink it to make it smaller so that it will fit in better with the post. However, I did a test post and kept the "full" size image, but it also shrinks when clicked.
Here's one example: http://costofcollege.wordpress.com/2012/01/11/for-job-security-its-better-to-make-technology-than-to-use-it/
I use Under the Influence theme. Any ideas about what has happened and how I can fix this problem?
The blog I need help with is costofcollege.wordpress.com.
