Hi Mike,

What is the size in pixel of your image. A jpeg file of 5MB is probably very large and there may not be anything that can be done as this is just a lot of memory to manage. You should definitely limit the zooming. The next release will have an overview panel which will be a "smarter" way to zoom by only zooming part of an image instead of the entire image.

Best regards,
