I don't use microsoft word, my last computer didn't have it and I used paint.
There have been a lot of discussion about indexing digitals; I have been spending the last month using a method shared on here in this posting:
SU! Stamped Images book by Christhedolllady at Splitcoaststampers
posting number 11, by Sarah, has a fantastic system, though not speedy at all. I love it and catagorize mine by companies names, so I can find what images to use for challenges. Then I create my own indexing typed system for cross reference. I don't do excel or anthing like that to know if that could be faster. So, you are using microsoft work, to resize images, I gather. I wouldn't be saving all those images on youor computer, but, a USB memory stick,
at least. It probably slows your computer, and if it crashes, everything is gone.
