Nope. You can turn off the grid and drag it in with alt and you might get better sizing results, but the easiest way is to right click the graphic and set its dimensions in either pixels or units. If you have things you use often that you need at a particular size, you can associate a correctly sized one with a character as its default token and drag it in to the map from the journal as needed. I do this for Spell Effect Templates. If you want graphics to drag into the repo at their pixel size, you'd need to pursue that as an enhancement via the Suggestions & Ideas Forum. Be sure to post a link here to the suggestion as I'm sure lots of people (me included) would love to have that functionality. There might be a suggestion for that already...
