To check file sizes as uploaded, you can get some browsers to tell you. For example, in Firefox you can Ctrl-click on the picture and pick Properties, and it will tell you the size in bytes. (39628 in your case, so you're just inside the limit).
All you can get easily out of Safari is the size in K from the activity window.
If you're willing to use the terminal instead of Finder, ls -l will also give you the count you're after.
