Hi @danielh, welcome to the community and thanks for the detailed issue. When you get a chance, please [introduce yourself here](https://forum.getodk.org/t/-/6671). I'd also encourage you to add a real picture as your avatar because it helps build community!

To solve your problem, re-rerun the v1.4.15 installer and edit the `ODKAggregate/default/WEB-INF/appengine-web.xml` file to use bigger machines. The process id documented in greater detail at [https://docs.opendatakit.org/aggregate-boost-performance/#web-server-size](https://docs.opendatakit.org/aggregate-boost-performance/#web-server-size).

I'd also strongly encourage you to setup nightly backups with [Briefcase via the CLI](https://docs.opendatakit.org/briefcase-using/#working-with-the-command-line) because, well, App Engine's performance with managing very large files can be miserable. Backups also make it easier for you to safely upgrade to newer versions of Aggregate.

And speaking of newer versions, note that [Google will be deprecating the Java 7 runtime in Jan 2019](https://cloud.google.com/appengine/docs/deprecations/java7) and I believe Aggregate v1.4.15 uses that runtime. And if that isn't compelling, newer versions of Aggregate have security improvements and improvements to data export.

Finally, if you don't need high resolution pictures, you might want to consider resizing them on the device. [https://docs.opendatakit.org/form-question-types/#scaling-down-images](https://docs.opendatakit.org/form-question-types/#scaling-down-images) has more.
