Need Photo Help!

My sister has a Photo CD from the drug store that has our reunion photos on it.  Unfortunately, she got it as a slideshow CD so they are .htm files. Is there some way to get them off of there as .jpg or even .bmp files that I can explain to her?  She has no clue about any of this stuff, and being four hours away, I can't sit down and see what is what. 

Any help is much appreciated!  She took a ton of family pictures and I want copies of them.

Thanks!
