Corrupt upload of large images

Hi, I’ve got an upload-button which will upload and save a file in /uploads/.
However, I experience that multiple times the complete image is not uploaded - only the first part of the image shows - the rest of it is corrupt. This seem to happen mostly when uploading large images (>2MB).

Feel free to have a look at https://fitslave.backendless.app/test/ using username d@dlevy.no and password “access”.
There is a couple of images there now which was corrupted on upload.

Hello,

How did you upload the image? Did you do in Backendless Console or using the API?

Regards,
Mark

Its done by the upload-button in the app. Created with UI-builder.

Looks like the page makes multiple requests to upload the file. As a result, I suspect the file gets corrupt:

You are right - of course. Thanx!
