Hi
These very few ways to edit a JPG in Excel there are / is a drawing and picture toolbar whic can edit a bit more than that you will need software to do this
Windows come fitted with MSPaint which will cut and crop few bit but simple enough.
Maybe consider other software if you need more, I do not tell guys to buy ive see ive no right to say that!
I will not tell you what to buy either, but of cause i will tell you what i use / have used, but thats my choice, not definative, it ALL UP TO YOU
Paint Shop Pro [Jasc] $130 USD
Photoshop [Adobe] $700 USD
There are always FREE software to do this in the UK on PC magazne cover disc;'s worth looking at!!
