Julie - You may want to try the "Optimize embellishment sizes" option when exporting your template. This options will analyze all of the embellishments added to the project and resize the files to the maximum dimensions currently being used in the template. This can significantly decrease the size of the exported template file, making it easier to upload and share with others.
While it is true that if people want to then "enlarge" those embellishments, the quality won't be quite as good, however the idea is that with a "freebie" that could be totally acceptable. In fact, we resize them down but also pad in a bit of leeway so increases of say 10-20% are totally undetectable. It's an option for templates that are otherwise too large and packed with stuff to be uploaded.
