Look at http://cran.r-project.org/web/packages/ReadImages/index.html and
http://cran.r-project.org/web/packages/qgraph/index.html

It seems you have an ancient version of qgraph and that depends on a 
package which has not been available for about a year.

You failed to give the 'at a minimum' information required in the 
posting guide, so we can only guess how you managed this.  Perhaps

'f you are using an old version of R and think it does not work 
properly, upgrade to the latest version and try that, before posting.'

applies?
