I'm not sure if the issue is with Craft 3, the Preparse plugin, or me, so I'm posting here first.
I have a front-end form that includes an Assets field used to upload images. The entry type contains Preparse fields.
When the Preparse plugin is enabled and I submit the front-end form with an image, I get this error:
Image Exception – craft\errors\ImageException The file "assets5bcf19ef8f6bc6.04658934.jpg" does not appear to be an image.

The entry still gets created and the .jpg file is uploaded as expected.
I don't have any issues when creating entries via the CP.
If I disable the Preparse plugin and submit the front-end form, the error does not appear.
If I upload a .pdf file instead of a .jpg while the Preparse plugin is enabled, I don't get an error.
Therefore, it appears to be an issue with the Preparse plugin and image files in Craft 3 front-end forms (tested both .jpg & .png).
How can I fix this?
