On the top row of tabs you'll click Insert.
On the drop down menu click Image.
You'll see your image address and also an area to add your own Dimensions.
You need only click the first box to add the width. Constrain proportions will keep the height in reltion to the width. Image width over 500 are kinda too big.
Click OK and you're done
wow- thanks- didn’t know it could do that-
i just always clicked in the box and pasted the image- and they come out whatever the image size is- sometimes catching me off guard because too large-
