Rearranging figures - reassurance

[Brian Kneller]

Hello,
I am using the document class books for my thesis and I have numbered my figures with chapter number first and incremental number second - ie  Fig 2.3 for graphic 3 in chapter 2. I wish to delete and change the order of  figs . I have done this and manually updated the links  (for the TOC ?). Are there any snags I could encounter by moving figures around like this?

Thanks in advance
